Takeshita, T; Umeda, T; Hara, MFabrication of a dye-sensitized solar cell containing a noncarboxylated spiropyran-derived photomerocyanine with cyclodextrinJOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY A-CHEMISTRYDye-sensitized solar cell; Photomerocyanine; Cyclodextrin; Inclusion complex; IsomerizationNANOPARTICLESThe fabrication, photovoltaic conversion, and photo-response of dye-sensitized solar cell (DSSC) containing a noncarboxylated spiropyran 1,3,3-trimethylindolino-beta-naphthopyrylospiran (1) and carboxymethy1-beta-cyclodextrin sodium salt (CM-beta-CD) were investigated for the first time. In fact, we found the adsorption of photomerocyanine form (PMC) of 1 and inclusion complexes between the PMC and CM-beta-CD (PMC/CM-beta-CD) to the TiO2 surface. The formation of PMC/CM-beta-CD was confirmed by fluorescence spectroscopy. The incident photon-to-current conversion efficiency (IPCE) of the PMCcontaining DSSC obtained 4.1% under 570-nm light irradiation, and the highest IPCE reached 11.1% by inclusion effect of CM-beta-CD. Similar, the fillfactor and the open-circuit voltage were improved by CM-beta -CD layer. The IPCE value of PMC/CM-beta-CD-containing DSSC was decreased by visible light treatment, and it was considered that decrease of IPCE values are attributed to the formation of PMC isomer. Therefore, we demonstrated the photovoltaic conversion and photoresponsivity of the DSSC by incorporating a noncarboxylated PMC with inclusion effect of CM-beta-CD layer. (C) 2016 Elsevier B.V.

Chen, CC; Chang, FC; Peng, CY; Wang, HPConducting glasses recovered from thin film transistor liquid crystal display wastes for dye-sensitized solar cell cathodesENVIRONMENTAL TECHNOLOGYrecovered ITO; conducting glass; DSSC; Nickel; Ni@CINDIUMTransparent conductive glasses such as thin film transistor (TFT) array and colour filter glasses were recovered from the TFT-liquid crystal display panel wastes by dismantling and sonic cleaning. Noble metals (i.e. platinum (Pt)) and indium tin oxide (ITO) are generally used in the cathode of a dye-sensitized solar cell (DSSC). To reduce the DSSC cost, Pt was replaced with nano nickel-encapsulated carbon-shell (Ni@C) nanoparticles, which were prepared by carbonization of Ni2+--cyclodextrin at 673K for 2h. The recovered conductive glasses were used in the DSSC electrodes in the substitution of relatively expensive ITO. Interestingly, the efficiency of the DSSC having the Ni@C-coated cathode is as high as 2.54%. Moreover, the cost of the DSSC using the recovered materials can be reduced by at least 24%.TAYLOR & FRANCIS LTDABINGDONENVIRON TECHNOLEnviron.

The formation of the complex in the solid state and when adsorbed on TiO2 was characterized using steady and picosecond time-resolved emission techniques, as well as time dependent DFT calculations. The molecular-level insulation has led to a small enhancement in the energy-conversion performance of the fabricated DSSC with the best results being an increase in the open circuit voltage (Voc) from 0.7 to 0.8 V. The importance of the present investigation lies in the unique spectroscopic characterizations of the examined materials in the solid state.Saleh, Na'il/0000-0003-3282-1156; Graham, John/0000-0002-8786-6610;SPRINGER/PLENUM PUBLISHERSNEW YORKJ FLUORESCJ.

Takeshita, T; Umeda, T; Oonishi, N; Hara, MApplication of a Noncarboxylated Dye Compound in a Dye-Sensitized Solar Cell Containing a Cyclodextrin LayerINTERNATIONAL JOURNAL OF PHOTOENERGYTIO2 NANOPARTICLES; ORGANIC-DYES; PERFORMANCE; EFFICIENCY; COMPLEXESWe report the fabrication and characterization of a dye-sensitized solar cell containing a carboxymethyl-beta-cyclodextrin sodium salt (CM-beta-CD) layer and a noncarboxylated dye compound (tris(2,2'-bipyridyl) ruthenium(II) dichloride hexahydrate (Ru-dye)). The values of the incident photon-to-current conversion efficiency (IPCE) of the Ru-dye/CM-beta-CD-containing device measured under 450 and 490 nm light irradiation were, respectively, 2.35% and 3.33%. The IPCE was due to the absorption of Ru-dye in ethanol solution. In contrast, the IPCE of the device that was prepared without the CM-beta-CD layer measured under 450 nm irradiation was approximately three times smaller. Accordingly, the current findings demonstrate the application of a noncarboxylated dye compound in DSSCs incorporating a CM-beta-CD layer.HINDAWI LTDLONDONINT J PHOTOENERGYInt. J.

Hara, M; Takeshita, T; Umeda, TEffect of cyclodextrin cavity size on the photovoltaic performance of unanchored ruthenium(II) polypyridine complex-containing dye-sensitized solar cellsJOURNAL OF PHOTONICS FOR ENERGYdye-sensitized solar cell; cyclodextrin; unanchored photosensitizing dye; cavity sizeNANOPARTICLESWe report the effect of cyclodextrin (CD) cavity size on the photovoltaic performance of dye-sensitized solar cells (DSSCs) containing inclusion complexes of tris(2,2'-bipyridyl) ruthenium(II) ([Ru(bpy)(3)](2+)) in various CDs ([Ru(bpy)(3)](2+)/CD). The incident photon-to-current conversion efficiency (IPCE) of the [Ru(bpy)(3)](2+)-containing DSSC at 460 nm was calculated to be 8.1%, and this value was enhanced by the formation of [Ru(bpy)(3)](2+)/CD. The IPCE values of [Ru(bpy)(3)](2+)/alpha-CD-containing, [Ru(bpy)(3)](2+)/beta-CD-containing, and [Ru(bpy)(3)](2+)/gamma-CD-containing DSSCs were 8.8%, 8.9%, and 11.2%, respectively. It was concluded that the difference of IPCE values of [Ru(bpy)(3)](2+)/CD-containing DSSCs were caused by the CD cavity size, which affected the host-guest interaction between [Ru(bpy)(3)](2+) and the CD. These findings indicated that the cavity size of gamma-CD is suitable to promote the photovoltaic conversion of DSSCs containing an unanchored photosensitizing dye with nonplanar molecular structure such as ruthenium(II) polypyridine and diimine copper(I) complexes.

Kumavat, PP; Baviskar, PK; Sankapal, BR; Dalal, DSFacile synthesis of D-π-A structured dyes and their applications towards the cost effective fabrication of solar cells as well as sensing of hazardous Hg(II)RSC ADVANCESORGANIC-DYES; PHOTOVOLTAIC PERFORMANCE; SUPRAMOLECULAR CATALYST; GOLD NANOPARTICLES; BETA-CYCLODEXTRIN; ELECTRON-TRANSFER; AQUEOUS-MEDIUM; FLUORESCENT; DERIVATIVES; FILMSWe design and establish an environmentally benign synthesis of new D-pi-A dyes containing imidazole derivatives structured to triphenylamine (TPA) as a donor and cyano acrylic groups acting as acceptors without using any toxic catalysts. These newly synthesized imidazole derivatives are anchored on TiO2, towards a cost effective dye sensitized organic solar cell, and achieve 0.22% solar-light to electricity conversion efficiency under standard AM 1.5G irradiation (100 mW cm(-2)). The most widely significant findings of this study are high thermal stability, smooth surface, strong intramolecular interaction between dyes and TiO2 which improve the performance of the dye sensitized solar cell. The metal ion sensing properties of both the dyes were investigated optically using UV-Vis absorption spectroscopy. The results exhibited high selectivity and sensitivity towards toxic Hg(II) ions compared to other tested metal ions. The binding constants (K-a) of receptors 1 and 2 are 2.53 x 10(5) M-1 and 0.99 x 10(5) M-1, respectively, which are reported with the help of Benesi-Hildebrand method.Sankapal, Babasaheb R./0000-0002-7464-9633;ROYAL SOC CHEMISTRYCAMBRIDGERSC ADVRSC Adv.2016610810645310646410.1039/c6ra18712ahttp://dx.doi.org/10.1039/c6ra18712a
Shahat, MA; Dardeer, HM; Rashwan, GM; Ghitas, A; Taha, AGUnveiling the Synergistic Effects of Novel β-Cyclodextrin Co-sensitizers on Anthrone-Based Dye-Sensitized Solar Cells (DSSCs) with Microstructural ModificationsJOURNAL OF INORGANIC AND ORGANOMETALLIC POLYMERS AND MATERIALSDye-sensitized solar cells; Anthrone-2chloro aniline; Anthrone-2amino salicylic acid; Beta-cyclodextrin; Graphene oxide; Photovoltaic performanceMETHYLENE-BLUE DYE; COUNTER ELECTRODES; INCLUSION COMPLEXES; PERFORMANCE; PHOTOCATALYST; ENHANCEMENT; ANTHRACENE; REDUCTION; KINETICS; BINARYDye-sensitized solar cells (DSSCs) offer an intriguing alternative to traditional solar cell technologies, particularly for applications where flexibility, transparency, and cost-effectiveness are paramount. In this regard, this study aims to address their limitations and further enhance their performance for wider adoption in renewable energy systems. Therefore, for the first time, innovative low-cost, platinum-free counter electrodes (CEs) of anthrone-based composites, involving 2chloroaniline@beta-CD, 2amino Salicylic acid@beta-CD, 2-nitroaniline@beta-CD, or 4-nitroaniline@beta-CD, to enhance the efficiency of DSSCs. Physical observations of microstructure, 1HNMR, morphology, melting point, electrical, optical characteristics, along with photocurrent density-photovoltage (J-V) characteristic measurements were conducted on these components in the DSSCs structure. In the meantime, the blended anthrone chain system's energy levels were optimized by including beta-CD with these matrixes, revealing improved PV performance compared to DSSCs with a pristine anthrone. Out of each of the developed DSSCs, the one constructed with co-sensitizers that included 2chloroaniline@beta-CD exhibited the highest efficacy. UV absorption spectra shifts, optimized band gap (i.e., 2.59 eV), rapid variations in surface roughness, and the general pattern of grain size variation in relevant SEM images are all in line with DSSC gains, as is their reliance on dye absorption behaviours over several optical layers. Once beta-CD was added to the Anthrone@2chloroaniline composite, the DSSC performance significantly improved, with the power conversion efficiency increasing from 2.65 to 4.12%, the charge transfer resistance (Rct) decreasing from 30.26 ohm to 27.81 ohm, and the short-circuit current density (Jsc) rising from 9.63 to 12.41 mA/cm2, confirming that beta-CD enhances electron transfer and reduces interfacial recombination. The recorded variations in cell features such as Jsc levels, including diverse co-sensitizers, may be assigned to the first stage of the photogenerated carrier in terms of the light-harvesting ability of dye-anchored photo-layers along with charge transportation yield. Blending with beta-CD improved charge carrier mobility and suppressed recombination in anthrone hybrids by facilitating efficient charge separation, leading to longer carrier lifetimes, reduced resistive losses, and enhanced DSSC performance-supporting the development of more resilient and sustainable energy technologies.SPRINGERDORDRECHTJ INORG ORGANOMET PJ.
