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.

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.
