Abstract
AbstractThe synthesis and spectroscopic characterization of an innovative ball-type cobalt metallophthalocyanine 4, bridged by four 1,2-bis(2-hydroxymethyl)-O-carborane (HMOC) 1 units, has been achieved. The synthesized compound 4 was characterized structurally and electronically using elemental analysis, UV-Vis absorption spectroscopy, FT-IR spectroscopy, MALDI-TOF mass spectrometry, EPR spectroscopy and magnetic susceptibility. The photovoltaic performance of the newly synthesized compound in dye-sensitized solar cells was investigated. In order to clarify the effect of dye-sensitization time on photovoltaic performance parameters, the sensitization time was varied from 12 to 60 h and the performance parameters were investigated. It was found that sensitization time had a strong effect on the main performance parameters. The best photovoltaic performance was achieved after sensitization for 36 h (short circuit current density, 5.41 mA cm−2; overall conversion efficiency, 3.42%). Computational UV-Vis absorption spectra of the molecule was calculated using time dependent density functional theory and was found consistent with measured UV-Vis spectra.

Abstract
Herein, we report the design and synthesis of four new thiophene-bridged D-π-A configured organic dyes T1-4 comprising different donors, π-spacers and anchoring units, as potential sensitizers and co-sensitizers for DSSCs. The current work also highlights their structural, photophysical, thermal, electrochemical, theoretical, and photoelectrochemical studies, including evaluation of their structure-property relationships. The optical results revealed that the dyes T1-4 display λabs and λemi in the range of 402-461 nm and 556-575 nm, respectively, with a bandgap in the order of 2.31-2.58 eV. Furthermore, the results showed that the dyes possess all the pre-requisites to act as sensitizers/co-sensitizers. Among the tested dyes, the device based on sensitizer T2 achieved the highest PCE compared to the other three dyes, under the standard conditions. Furthermore, their co-sensitized devices were fabricated by co-adsorbing them with the well-known Ru-based MH-12 sensitizer and interestingly the co-sensitizer T3 carrying an alkoxy group and a barbituric acid anchor displayed the highest PCE of 8.79%, which is much higher than that of MH-12 alone (8.18%). Conclusively, the study furnishes a deeper understanding of the intricacies involved in the structural modification of sensitizers/co-sensitizers in achieving an enhanced performance of the devices.

Abstract
Photocurrent ( Jsc) and photovoltage ( Voc) are two important parameters for dye-sensitized solar cells (DSSCs) to achieve high power conversion efficiencies (PCEs). Herein, we synthesize four novel porphyrin dyes, XW36-XW39, using an N-phenyl-substituted phenothiazine donor to pursue higher PCE. For XW36 and XW37, the N-phenyl group is wrapped with two ortho-alkoxy chains. In contrast, it is substituted with a para-alkoxy group in XW38 and XW39. The phenothiazine wrapping in XW36 and XW37 induces more serious distortion, which is beneficial for anti-aggregation but unfavorable for the electron transfer from donor to a porphyrin framework. Thus, individual porphyrin dyes XW36 and XW37 exhibit efficiencies of 9.05 and 9.58%, respectively, lower than those of 9.51 and 10.0% achieved for XW38 and XW39, respectively. Besides, the introduction of a methyl group into a benzoic acid acceptor unit is conducive to anti-aggregation and thus improves the Voc and efficiencies. Therefore, higher efficiencies were achieved for XW37 and XW39, compared with XW36 and XW38, respectively. Interestingly, although the individual XW36 dye shows a lowest efficiency among the four dyes, a highest efficiency of 11.7% was obtained for XW36 on the basis of synergetic adsorption with chenodeoxycholic acid and PT-C6 because of simultaneously improved Jsc and Voc, which may be ascribed to the lowest dye-loading amount of XW36 among all of these porphyrin dyes, with the largest vacancy area left on the TiO2 surface available for cosensitizer PT-C6, resulting in a highest Jsc. The high efficiency of 11.7% is one of the highest efficiencies using I-/I3- electrolytes in DSSCs. These results provide an effective strategy for developing efficient DSSCs by the targeted coadsorption and cosensitization of porphyrin sensitizers optimized through introducing a bis( ortho-alkoxy)-wrapped phenyl group into the phenothiazine donor and/or methyl groups into the benzoic acid acceptor unit.

Abstract
Versatile conjugated small molecules bearing cyanopyridone core (CP1-5), composed of various donor/acceptor moieties at position -4 and -6 have been designed, developed and characterized. Their solvatochromic studies were conducted and analyzed using Lippert-Mataga, Kamlet-Taft and Catalan solvent scales and interesting results were obtained. The polarizability/dipolarity of the solvent greatly influenced the spectra. The electrochemical studies were carried out using cyclic voltammetry to calculate the HOMO-LUMO energy levels. The study revealed that the synthesized conjugated small molecules possess low lying HOMO energy levels which can be exploited for application in various fields of optoelectronics.

Abstract
Two organic D-A-π-A sensitizers LS-2 and WS-5 containing N-octyl substituted phthalimide and benzotriazole as auxiliary electron withdrawing units with similar dimension and structure architecture were systematically studied, focusing on photophysical and electrochemical as well as photovoltaic properties in nanocrystalline TiO(2)-based dye-sensitized solar cells (DSSCs). Interestingly, with similar five-member benzo-heterocycles, the two auxiliary acceptors of phthalimide and benzotriazole play exactly different roles in absorption and intramolecular charge transfer: (i) in contrast with WS-5 delocalized throughout the entire chromophore, the HOMO orbital of LS-2 is mainly located at the donor part due to the twist conformation with the existence of two carbonyl groups in phthalimide; (ii) the dihedral angles of "D-A" plane and "A-π" plane in LS-2 further suggest that the incorporation of phthalimide moiety results in curvature of electron delocalization over the whole molecule, in agreement with its blue-shifted, relatively narrow absorption spectra and low photocurrent density; (iii) in contrast with the beneficial charge transfer of benzotriazole in WS-5, the phthalimide unit in LS-2 plays an oppositely negative contribution to the charge transfer, that is, blocking intramolecular electron transfer (ICT) from donor to acceptor to some extent; and (iv) in electrochemical impedance spectroscopy, the incorporated benzotriazole unit enhances electron lifetime by 18.6-fold, the phthalimide only increases electron lifetime by 5.0-fold. Without coadsorption of chenodeoxylic acid (CDCA), the DSSCs based on WS-5 exhibited a promising maximum conversion efficiency (η) of 8.38% with significant enhancement in all photovoltaic parameters (J(SC) = 15.79 mA cm(-2), V(OC) = 791 mV, ff = 0.67). In contrast, with the very similar D-A-π-A feature changing the additional acceptor from benzotriazole to phthalimide unit, the photovoltaic efficiency based on LS-2 was only 5.11%, decreased by 39%, with less efficient photovoltaic parameters (J(SC) = 10.06 mA cm(-2), V(OC) = 748 mV, ff = 0.68). Therefore, our results demonstrate that it is essential to choose proper subsidiary withdrawing unit in D-A-π-A sensitizer configuration for DSSCs.
