The studied device combines materials typically used in dye-sensitized solar cell (DSSC) and an electrochromic (EC) layer of WO3. First, We examine if the dye could be attached directly to the EC layer forming an efficient photoactive layer to colour the PC device. Further, different TiO2 layers have been coated on the EC layer to enhance dye loading and two different sol-gel TiO2 layers and the post-treatment of the EC layer with a titanium(IV) chloride tetrahydrofuran complex have been studied. The dye loading of different photoactive layers and their efficiencies in DSSC have been evaluated and discussed with regard to the performance of the PC devices. The results confirmed that the dye could be attached to the WO3 layer, but that the voltage of the DSSC is too low to colour the device. To realize a functioning PC device, the addition of TiO2 is necessary. The best performance (deep and fast colouration) is obtained for a PC device with a TiO2 sol-gel layer; the solar transmittance of the PC device decreases from 57% to 7.5% in under three minutes. According to our knowledge, this is the first study of the impact of the photoactive layer on the photochromic glazing's response. | [Hocevar, Mateja; Krasovec, Ursa Opara] Univ Ljubljana, Fac Elect Engn, Trzaska Cesta 25, Ljubljana 1000, Slovenia; [Bogati, Shankar; Georg, Andreas] Fraunhofer Inst Solar Energy Syst ISE, Heidenhofstr 2, D-79110 Freiburg, Germany | University of Ljubljana; Fraunhofer Gesellschaft; Fraunhofer Germany; Fraunhofer Institute of Solar Energy Systems | Hocevar, M i˜A—’˜ŽÒjAUniv Ljubljana, Fac Elect Engn, Trzaska Cesta 25, Ljubljana 1000, Slovenia. | mateja.hocevar@fe.uni-lj.si | ; Opara Kra?ovec, Ur?a/GZG-5098-2022 | Opara Krasovec, Ursa/0000-0003-1061-6784; | EU FP7 project WINSMART [314407]; Slovenian Research Agency [P2-0244] | EU FP7 project WINSMART; Slovenian Research Agency(Slovenian Research Agency - Slovenia) | The authors gratefully acknowledge the support from the EU FP7 project WINSMART under Grant No. 314407.

Internal storage integration can offer highly robust systems at substantially low cost if external batteries are replaced by internal ones. Despite excellent photovoltaic power conversion efficiencies of dye-sensitized solar cells, they are short of storage capability. In this work, we demonstrate an integrated solar storage cell that can potentially deliver solar power even in darkness owing to its integrated energy storage capability. The cell was built upon the dye-sensitized solar cell platform using a photochromic WO3 electrode and had the ability to simultaneously generate and store charges during the day and discharge the stored charges during night. Specifically, three different batches of WO3 nanoparticles, each of unique particle size, were investigated in terms of their compatibility with the solar storage cell and built-in storage capacity. Our results revealed that the solar storage cell with the largest WO3 particle size (similar to 100 nm) exhibited the best transient voltage-current characteristics. On the other hand, intermediate WO3 particle size (60-95 nm) displayed the best storage capacity when undergoing a prolonged photocharging. These comparative investigations shed light on the morphological difference in electrode, active surface area, porosity-dependent electron transport, and redox diffusion coefficient that have a significant impact on the photo/electrochemical properties of the electrodes.

These novel solar cells have already achieved efficiencies above 4%, and there are multiple pathways to improve the performance. In this work, we conduct a full characterization of DSSCs with the photochromic dye NPI, combining electrical impedance spectroscopy (EIS) and intensity-modulated photocurrent spectroscopy (IMPS). We argue that the inherent properties of the photochromic dye, which result in a modification of the functioning of the solar cell by the optical excitation that also acts as a probe, pose unique challenges to the interpretation of the results using conventional models. Absorption of light in the visible range significantly increases when the NPI dye is in the activated state; however, the recombination rate also increases, thus limiting the efficiency. We identify and quantify the mechanism of enhanced recombination when the photochromic dye is activated using a combination of EIS and IMPS. From the comparison to a state-of-the-art reference dye (RK1), we were able to detect a new feature in the IMPS spectrum that is associated with the optical activation of the photochromic dye, providing a useful tool for assessing the electronic behavior of the device under different conditions of light excitation. This study provides guidelines to adequate characterization protocols of photochromic solar cells and essential insights on the interfacial electronic processes. | [Riquelme, Antonio J.; Sanchez-Fernandez, Patricia; Escalante, Renan; Oskam, Gerko; Anta, Juan A.] Univ Pablo Olavide, Area Quim Fis, E-41013 Seville, Spain; [Mwalukuku, Valid Mwatati; Liotier, Johan; Demadrille, Renaud] Univ Grenoble Alpes, CEA, Mol Syst & NanoMat Energy & Hlth SyMMES, Interdisciplinary Res Inst Grenoble IRIG,CNRS, F-38000 Grenoble, France; [Oskam, Gerko] CINVESTAV, IPN, Dept Appl Phys, Merida 97310, Yucatan, Mexico | Universidad Pablo de Olavide; CEA; Centre National de la Recherche Scientifique (CNRS); Communaute Universite Grenoble Alpes; Universite Grenoble Alpes (UGA); Instituto Politecnico Nacional - Mexico; CINVESTAV - Centro de Investigacion y de Estudios Avanzados del Instituto Politecnico Nacional | Anta, JA i˜A—’˜ŽÒjAUniv Pablo Olavide, Area Quim Fis, E-41013 Seville, Spain.;Demadrille, R i˜A—’˜ŽÒjAUniv Grenoble Alpes, CEA, Mol Syst & NanoMat Energy & Hlth SyMMES, Interdisciplinary Res Inst Grenoble IRIG,CNRS, F-38000 Grenoble, France. | renaud.demadrille@cea.fr; anta@upo.es | Demadrille, Renaud/J-6088-2018; Oskam, Gerko/AAH-1315-2020; Riquelme, Antonio J/JLN-0309-2023; Anta, Juan/I-8561-2012; Liotier, Johan/GLS-3189-2022 | Demadrille, Renaud/0000-0002-7455-5709; Liotier, Johan/0000-0003-1747-693X; Oskam, Gerko/0000-0002-2105-5874; Anta, Juan/0000-0002-8002-0313; Riquelme, Antonio/0000-0003-2445-3664; Escalante, Renan/0000-0002-5100-5448; | Ministerio de Ciencia e Innovacion of Spain; Agencia Estatal de Investigacion (AEI); EU (FEDER) [PID2019-110430GB-C22, PCI2019-111839-2]; Junta de Andalucia [UPO-1259175]; Ministerio de Universidades; Universidad Pablo de Olavide through the Beatriz Galindo program [18/00077, BGP s18/00060]; Spanish Ministry of Education, Culture and Sports [FPU2017-03684]; ANR [ANR14-OHRI-0003-01]; European Research Council; French Embassy in Kenya through Campus France; European Union Horizon 2020 research and innovation program [832606]; CONACYT.

The compounds were characterized by FT-IR, UV-Vis, NMR spectroscopy, and LC-MS spectrometry techniques. The pH-dependent photochromic properties of the flavylium dyes were investigated through a UV-Vis spectroscopy study and revealed that they follow the same network of chemical reactions as anthocyanins upon pH changes. The structural and electronic properties of the dyes were investigated using density functional theory (DFT) and time-dependent density functional theory (TD-DFT). Geometry optimization calculation revealed that all dyes, regardless of the specie, flavylium cations or quinoidal bases, present a planar geometry. The photovoltaic performances of the dyes, in both flavylium and quinoidal base forms, were evaluated by the HOMO and LUMO energies and by calculating the light-harvesting efficiencies, the free energy change of electron injection, and the free energy change regeneration. The MO analysis showed that all dyes can inject electrons into the conduction band of the TiO2 upon excitation and that the redox couple can regenerate the oxidized dyes. The results obtained for the free energy change of electron injection suggest that the quinoidal bases should inject electrons into the semiconductor more efficiently than the flavylium cations. The values for the free energy change regeneration showed that the redox electrolyte can easily regenerate all dyes. Dipole moment analysis was also performed. DSSCs based on the dyes, in both flavylium and quinoidal base forms, were assembled, and their photovoltaic performances were evaluated by measuring the open-circuit voltage, the short circuit current density, the fill factor, and the energy conversion efficiency. Results obtained by both experimental and computational studies showed that the overall performances of the DSSCs with the quinoidal forms were better than those obtained with the flavylium cations dyes. | [Pausescu, Iulia; Todea, Anamaria; Dreava, Diana-Maria; Boboescu, Tania; Patcan, Bianca; Patcan, Larisa; Albulescu, Daiana; Badea, Valentin; Peter, Francisc; Medeleanu, Mihai] Politehn Univ Timisoara, Fac Ind Chem & Environm Engn, Carol Telbisz 6, Timisoara 300001, Romania; [Albulescu, Daiana; Ursu, Daniel] Natl Inst Res & Dev Electrochem & Condensed Matte, Dr A Paunescu Podeanu 144, Timisoara 300569, Romania; [Totos, Robert] Babes Bolyai Univ, Fac Chem & Chem Engn, Arany Janos 11, Cluj Napoca 400028, Romania; [Szolga, Lorant] Tech Univ Cluj Napoca, ETTI, Base Elect Dept, Optoelect Grp, 28 Memorandumului Str, Cluj Napoca 400114, Romania | Universitatea Politehnica Timisoara; Babes Bolyai University from Cluj; Technical University of Cluj Napoca | Medeleanu, M i˜A—’˜ŽÒjAPolitehn Univ Timisoara, Fac Ind Chem & Environm Engn, Carol Telbisz 6, Timisoara 300001, Romania.;Szolga, L i˜A—’˜ŽÒjATech Univ Cluj Napoca, ETTI, Base Elect Dept, Optoelect Grp, 28 Memorandumului Str, Cluj Napoca 400114, Romania. | lorant.szolga@bel.utcluj.ro; mihai.medeleanu@upt.ro | ; Szolga, Lorant/AAC-4482-2021; P?u?escu, Iulia/AAY-4637-2021; Badea, Valentin/NBX-2826-2025; T?t?s, R?bert/ABB-1042-2020; TODEA, Anamaria/H-5375-2016; Daiana, Albulescu/IAN-9812-2023; Todea, Anamaria/H-5375-2016; Medeleanu, Mihai/AHB-9177-2022; Ursu, Daniel/AAS-9265-2021; Peter, Francisc/C-9851-2011 | Badea, Valentin/0000-0002-6123-9774; Szolga, Lorant/0000-0002-9342-7403; Ursu, Daniel/0000-0002-5422-059X; Daiana, Albulescu/0000-0001-6154-2434; TODEA, Anamaria/0000-0001-7744-103X; Peter, Francisc/0000-0001-7248-2641 | Romanian Ministry of Education and Research, CCCDI-UEFISCDI, within PNCDI III [PN-III-P2-2.1-PED-2019-3037, 385PED, PN-III-P1-1.1-TE-2019-1573, TE 101] | Romanian Ministry of Education and Research, CCCDI-UEFISCDI, within PNCDI III(Consiliul National al Cercetarii Stiintifice (CNCS)Unitatea Executiva pentru Finantarea Invatamantului Superior, a Cercetarii, Dezvoltarii si Inovarii (UEFISCDI)) | This work was partially supported by a grant of the Romanian Ministry of Education and Research, CCCDI-UEFISCDI, project number PN-III-P2-2.1-PED-2019-3037, within PNCDI III, contract number 385PED, and partially supported by a grant of the Romanian Ministry of Education and Research, CCCDI-UEFISCDI, project number PN-III-P1-1.1-TE-2019-1573, within PNCDI III, contract number TE 101. | 65 | 6 | 6 | 3 | 25 | MDPI | BASEL | ST ALBAN-ANLAGE 66, CH-4052 BASEL, SWITZERLAND | 1996-1944 | MATERIALS | Materials | OCT | 2022 | 15 | 19 | 6985 | 10.3390/ma15196985 | http://dx.doi.org/10.3390/ma15196985 | 21 | |||||||||

Owing to its certain important combination of properties, TiO2 in the form of thin film has been found to be more attractive for a great variety of applications including photocatalytic degradation of organic pollutants in water as well as in air, dye sensitized solar cells (DSSCs), anti-fogging, superhydrophilic, photochromic, and optical applications. Although, a great number of techniques have been employed so far to fabricate TiO2 thin films, the cost of these thin films has not only been found to be dictated by the sophistication of the preparation method involved but also by the quick recombination of photo-generated electron/hole pairs, backward reactions involved, and the poor response of TiO2 to the visible light. Even though, metal loading, metal ion doping, anion doping, dye sensitization, composite semiconducting phenomenon, metal ion-implantation, addition of sacrificial reagents and carbonate salts to the reaction mixtures, etc., have been employed to improve the efficiency of the photocatalytic applications of TiO2 thin films, a clear-cut relationship between the properties of TiO2 thin films and their performance in a given application is yet to be established. In this article, some of the latest developments accomplished in the fabrication techniques, in the characterization and in the understandings of property and performance relationship of TiO2 thin film have been presented and discussed while citing certain of important references. | [Patil, Meghshyam K.; Shaikh, Sharekh] Dr Babasaheb Ambedkar Marathwada Univ, Dept Chem, Aurangabad 413501, Maharashtra, India; [Ganesh, Ibram] Int Adv Res Ctr Powder Met & New Mat ARCI, Lab Photoelectrochem PEC Cells, Hyderabad 500005, Andhra Pradesh, India | Dr. Babasaheb Ambedkar Marathwada University (BAMU); Department of Science & Technology (India); International Advanced Research Centre for Powder Metallurgy & New Materials (ARCI) | Patil, MK i˜A—’˜ŽÒjADr Babasaheb Ambedkar Marathwada Univ, Dept Chem, Subcampus Osmanabad, Aurangabad 413501, Maharashtra, India. | meghshyam_patil@yahoo.com | Patil, Meghshyam/H-2326-2018; Patil, Meghshyam Keshvarao/H-2326-2018 | Ganesh, Ibram/0000-0002-2976-5184; Patil, Meghshyam Keshvarao/0000-0002-3144-5016 | Department of Science and Technology, New Delhi under SERC FAST Track Scheme [SR/FT/CS-55/2010] | Department of Science and Technology, New Delhi under SERC FAST Track Scheme(Department of Science & Technology (India)Department of Science & Technology (DOST), Philippines) | MKP is thankful to the Department of Science and Technology, New Delhi for financial support from, under SERC FAST Track Scheme (SR/FT/CS-55/2010).

However, regardless of the technology considered, the optical transmission of semi-transparent solar cells is fixed during the fabrication process, and hence, cannot adjust to variations in daylight or weather conditions. This becomes an issue when applications such as photovoltaic windows are envisioned. Previously, it has been reported that the use of photochromic naphthopyran dyes in dye-sensitized solar cells (DSSC) allows for the fabrication of semi-transparent devices capable of modulating their light transmission and energy production depending on light intensity. Herein, a series of naphthopyran dyes with an identical pi-conjugated backbone and varying alkyl substituents is reported. Using this molecular engineering strategy, the control of the discoloration kinetics of the photochromic dyes and the reduction of undesirable recombination processes when utilised in solar cells is demonstrated. The clear photochromic-photovoltaic structure-property relationships for these new photosensitizers is established and they are shown to demonstrate improved photovoltaic performances and photochromic responses in DSSC with notably faster discoloration than previously reported. For the first time with photochromic molecules, the co-sensitization of the electrodes is explored and the highest power conversion efficiency for a photochromic DSSC is reported, reaching up to 4.34% under standard conditions. | [Mwalukuku, Valid M.; Liotier, Johan; Kervella, Yann; Huaulme, Quentin; Haurez, Alix; Demadrille, Renaud] Univ Grenoble Alpes, CNRS, CEA, SyMMES, 17 Rue Martyrs, F-38000 Grenoble, France; [Riquelme, Antonio J.; Anta, Juan Antonio] Univ Pablo de Olavide, Area Quim Fis, Seville 41013, Spain; [Narbey, Stephanie] Solaronix SA, Rue Ouriette 129, CH-1170 Aubonne, Switzerland | Centre National de la Recherche Scientifique (CNRS); CEA; Communaute Universite Grenoble Alpes; Universite Grenoble Alpes (UGA); Universidad Pablo de Olavide | Demadrille, R i˜A—’˜ŽÒjAUniv Grenoble Alpes, CNRS, CEA, SyMMES, 17 Rue Martyrs, F-38000 Grenoble, France. | renaud.demadrille@cea.fr | Anta, Juan/I-8561-2012; Liotier, Johan/GLS-3189-2022; Riquelme, Antonio J/JLN-0309-2023; Demadrille, Renaud/J-6088-2018 | Anta, Juan/0000-0002-8002-0313; MWALUKUKU, Valid Mwatati/0000-0002-8149-5652; KERVELLA, Yann/0000-0001-5003-8320; Riquelme, Antonio/0000-0003-2445-3664; Liotier, Johan/0000-0003-1747-693X; Demadrille, Renaud/0000-0002-7455-5709 | CEA; European Research Council (ERC); European Union's Horizon 2020 research and innovation programme [832606]; EU (FEDER) [PID2019-110430GB-C22, PCI2019-111839-2]; Spanish Ministry of Education, Culture and Sports [FPU2017-03684]; European Research Council (ERC) [832606] Funding Source: European Research Council (ERC) | CEA(CEA); European Research Council (ERC)(European Research Council (ERC)); European Union's Horizon 2020 research and innovation programme(Horizon 2020); EU (FEDER)(European Union (EU)); Spanish Ministry of Education, Culture and Sports(Spanish Government); European Research Council (ERC)(European Research Council (ERC)) | J.L. acknowledges CEA for funding through a CFR PhD grant.

In order to anchor dye on CdS NWs nano-network, solution chemistry has been used in an easy and effective manner. The sensitizing capability of synthesized materials has been evaluated using optical and electrochemical studies, density functional theory (DFT) simulations, and photovoltaic performances. In line with a detailed analysis of fabricated Dye sensitized solar cells containing T4PC a photovoltaic efficiency yields 4.35 times (0.487%) more than that of bare CdS NWs (0.112%), while the other devices having T3PC and T2PC have shown 3.0 (0.338%) and 2.40 (0.273%) times greater photovoltaic efficiencies, respectively under standard light illumination. The obtained results offer solid evidence in favour of boosting external quantum efficiency (EQE) and reflect good agreement with the optical studies. | [Mavazzan, Ahmedraza; Bayannavar, Praveen K.; Kamble, Ravindra R.; Madar, Suresh F.; Bheemayya, Lokesh] Karnatak Univ, Dept Studies Chem, Dharwad 580003, Karnataka, India; [Mendhe, Avinash C.] Hanyang Univ, Dept Civil & Environm Engn, ERICA, Ansan 15588, South Korea; [Mendhe, Avinash C.; Sankapal, Babasaheb R.] Visvesvaraya Natl Inst Technol, Dept Phys, Nanomat & Device Lab, South Ambazari Rd, Nagpur 440010, MS, India; [Pasha, K.

The photocatalytic competence of brookite relative to polymorphs anatase and rutile has generally been considered structurally and energetically unfavourable for reasons that remain largely unknown and unchallenged. However, the process of phase transformation and performance related cooperativity among all three polymorphs has recently unlocked alternative directions for exploring brookite photovoltaics. Here, we demonstrate the programmable re-configuration of anatase to quantum confined reduced graphene (rGO)-brookite and show it is entirely modulated by surface-driven effects. Key components to this mechanism suggest that the self-assembly of rGO-brookite quantum dots is defect driven through pathways that favour a direct-to-indirect band gap reversal resulting from the graphitization of brookite. The accompaniment of new bandgap characteristics under quantum confinement introduce new hybridized energy states at the graphitic carbon-brookite juncture by modulation of the intrinsic sp2 character to extrinsic sp3 clusters intermediate to graphene quantum dots (GQDs) and graphene oxide quantum dots (GOQDs). Evidenced by the intercalation of photochromic/fluorescent carbazole and anthracene moieties within the rGO framework by self-assembly, we show that the acquired fluorescence and luminescence properties of rGO-brookite are multi-emissive and reversibly quenchable under light excitation and from solvent polarity differences. Further, tuning the excitonic response of rGO-brookite by modulation of the photoluminescence (PL) signal intensity signifies coordinated interaction between localised carbazole and benz(a)anthracene moities which can undergo further structural refinement to adapt more optimally to both internal and external energy waves. Distinguishable by a large red-shift in the photoluminescent emission peak at lambda 479 nm in the NIR region, we infer that a photoelectron sink driven by the quantum confinement of a narrow band gap of 0.78 eV formed from the orbital overlap of unoccupied interfacial sites promotes strong e-h+ coupling in the hybridized defect structure imposing a high charge separation by hindering e-h+ recombination. Modulation of interlayer spacing between rGO sheets and the synergy of complexation between intercalated carbazole/benz(a)nthracene can be adapted to achieve rapid photodegradation characteristics for DSSC applications. | [Sonkaria, Sanjiv; Khare, Varsha] Seoul Natl Univ, Soft Foundry Inst, Coll Engn, Seoul, South Korea; [Lee, Tae Woo] Seoul Natl Univ, Dept Mat Sci & Engn, Seoul, South Korea; [Kumar, Aniket] Innovoja Sustainable Solut, White Rock, BC, Canada; [Hwang, Soo-Kyung] Seoul Natl Univ, Lab Adhes & Biocomposites, Major Environm Mat Sci, Seoul, South Korea; [Jablonski, Piotr G.] Seoul Natl Univ, Sch Biol Sci, Lab Behav Ecol, Seoul, South Korea; [Jablonski, Piotr G.] Museum & Inst Zool, Warsaw, Poland | Seoul National University (SNU); Seoul National University (SNU); Seoul National University (SNU); Seoul National University (SNU) | Sonkaria, S; Khare, V i˜A—’˜ŽÒjASeoul Natl Univ, Soft Foundry Inst, Coll Engn, Seoul, South Korea. | ssonkaria64@snu.ac.kr; khare@snu.ac.kr | Jablonski, Piotr/AAD-6768-2022; Lee, Tae-Woo/AAE-7298-2019 | Sonkaria, Sanjiv/0009-0002-8336-5509; | Ministry of Science, ICT and Future Planning [2022R1A2C1006090, 2017R1A2B4008801]; Basic Science Research Program through the National Research Foundation of Korea (NRF) - Ministry of Science, ICT & Future Planning [2017R1D1A1B03036226]; NRF Basic Research Program in Science and Engineering by the Ministry of Education [2021M3F7A1017476]; National Convergence Research of Scientific Challenges through the National Research Foundation of Korea (NRF) - Ministry of Science and ICT; Soft Foundry Institute | Ministry of Science, ICT and Future Planning(Ministry of Science, ICT & Future Planning, Republic of Korea); Basic Science Research Program through the National Research Foundation of Korea (NRF) - Ministry of Science, ICT & Future Planning(National Research Foundation of KoreaMinistry of Science, ICT & Future Planning, Republic of Korea); NRF Basic Research Program in Science and Engineering by the Ministry of Education; National Convergence Research of Scientific Challenges through the National Research Foundation of Korea (NRF) - Ministry of Science and ICT(National Research Foundation of Korea); Soft Foundry Institute | This work acknowledges support from the Basic Science Research Program through the National Research Foundation of Korea (NRF), funded by the Ministry of Science, ICT & Future Planning (No. 2022R1A2C1006090, 2017R1A2B4008801), and NRF Basic Research Program in Science and Engineering by the Ministry of Education (No. 2017R1D1A1B03036226).

Photochromic DSSCs & Smart Windows: Materials, Optics, and Measurement (with notes on CD×SP potential)
Overview
To co-optimize semi-transparent power generation and visual functions, researchers explore photochromic dyes in DSSCs and chromogenic glazing. This set highlights dye families (spiropyrans/spirooxazines, naphthopyrans, flavylium salts), TiO₂ phase/structure engineering (e.g., brookite, photonic trapping), and small-signal diagnostics (IMPS/IMVS). We also note integrated PV-storage concepts and the inherent trade-off between optical modulation and PCE. As context, cyclodextrin (CD) × spiropyran (SP) architectures promise “write-and-erase” displays, VPTT-driven phase control, and cascade FRET—potentially synergistic with photochromic windows/DSSCs.
Why it matters / Key points
- Dye design: SP/spirooxazine, naphthopyran, and flavylium motifs; carboxylate anchoring to TiO₂.
- Diagnostics: IMPS/IMVS quantify transport and recombination in photochromic DSSCs.
- Optical structuring: Brookite TiO₂ and band-gap reversal enable photonic trapping and spectral extension.
- Function integration: Toward PV + storage and reversible color switching in one platform.
- CD×SP advantages: Dual cross-linking, VPTT gating, and cascade FRET enable write-erase patterning (not all cited papers include CD; this is contextual potential).
