“…Quite a few challenges still remain before its commercialization, including cost, performance and 22 long-term stability. So far, various strategies are carried out to develop the low-cost, stable, and particularly highly efficient materials for different parts of DSSC, including the molecular engineering of novel dye sensitizers [126][127][128][129][130], the development of new redox shuttles [131][132][133][134][135][136], the construction of porous TiO 2 [137][138][139][140], and the search for low-cost, highly stable and catalytic CE materials [22,41,58,141]. Among the strategies for exploring new Pt-free CE materials, the family of carbon CE materials has become one of hot issues in photovoltaic research due to their low cost, anti-corrosion and high catalytic activity.…”

“…Moreover, it is easy to tune the absorption spectra as well as the HOMO and LUMO levels of dyes through the variation of D, p and A moieties [9]. Though some promising performance have been achieved by using organic sensitizers with coumarin [10], triphenyl amine [11e13], indoline [14,15], indole [16], phenothiazine [17], and carbazole [18] as the electron donors, researchers have been exploring new donors and acceptors for better solar-to-electricity efficiencies.…”

“…Another report has utilized TPA as luminescent material in organic light-emitting diodes [7]. TPA-based small molecules, with electron-donor architecture, are being studied in sensitized solar cells [8][9][10]. Other polymers with TPA units have been also reported, the polymers showed strong fluorescence in solid state and can be used as non-doped emitter to fabricate emitting diodes [11].…”

Several poly(thiophene) derivatives containing triphenylamine (TPA) as electron-donor were synthesized by chemical homopolymerization in CHCl 3 media using FeCl 3 as oxidizing agent. Monomers containing TPA bonded by imine groups to terminal thiophene, bithiophene, terthiophene units allows polymerization to be performed in conditions similar to thiophene. TPA units are regularly spaced in 2, 4, 6 and 8 thiophenyl units in the main chain. TPA electron-donor effect on the polymers chains, as compared to poly(thiophene) was studied. Polymers, labeled as poly(TPA-Th), poly(TPA-biTh) and poly(TPA-Terth) were characterized by 1 H-NMR, FT-IR and UV-visible spectroscopy, elemental analysis, thermal stability (TGA) intrinsic viscosity, differential scanning calorimetry (DSC) and electrochemically using cyclic voltammetry (CV). The characterizations are consistent with the proposed structures. The polymers exhibited different optical absorption.They exhibited low intrinsic viscosity, a different effective conjugation and high thermal stability. Moreover, the polymers displayed two redox processes with a redox potential lower than that of poly(thiophene). Highest Occupied Molecular Orbital (HOMO), Lowest Unoccupied Molecular Orbital (LUMO) and optical band gap (E g ) were measured and the obtained values were compared with those of poly(thiophene). The effect of the presence of TPA units in the thiophenyl chains on HOMO, LUMO, band gap, redox potential and on TGA is reported. To complete the series, HOMO/LUMO levels and band gap of a polymer containing TPA with 8 thiophenyl units in the chain were determined using theoretical calculations. The results proved that, with respect to poly(thiophene), it is possible to decrease HOMO and LUMO without changing the band gap, projecting itself as a potential polymer to be studied in organic photocells.
