  Carbazole donor and carbazole or bithiophene bridged sensitizers for dye-sensitized solar cells

  摘要：

  Three metal-free organic sensitizers consisting of carbazole as an electron donor, carbazole or bithiophene as the linker and cyanoacrylic acid as the electron acceptor and anchoring groups were designed and synthesized for use in dye-sensitized solar cells (DSSCs). The sensitizers were characterized by H-1 and C-13 NMR, MALDI-TOF (or HRMS), UV-Vis, photoluminescence, and electrochemistry. The HOMO and LUMO electron distributions of the sensitizers were calculated using density functional theory on a B3LYP level for geometry optimization. The photovoltaic performance of the sensitizers in operational liquid junction-based DSSCs under AM 1.5 G one-sun excitation (100 mW/cm(2)) indicate that the sensitizers are promising candidates for use in DSSCs. Sensitizers 1 and 2 produce a power conversion efficiency of 2.70% with a maximum IPCE of 75% at 450 nm, while sensitizer 3 has a power conversion efficiency of 2.23% with a maximum IPCE of 66% at 440 nm. The sensitizers thus exhibit excellent photon-to-current conversion efficiencies in the blue region of the spectrum and serve as candidates for further strategic optimization in tandem cells.

  Synthesis and computational studies of diphenylamine donor-carbazole linker-based donor–acceptor compounds

  摘要：

  The design, synthesis, and electronic spectra of a novel series of organic diphenylamine donor-carbazole linker-based donor-acceptor compounds are reported. The low-lying electronic transitions in these compounds are investigated using a combination of conventional steady-state absorption spectroscopy and tools of computational photochemistry. The electronic transitions were found to depend both on the nature of the acceptor moiety and the presence/absence of a carbazole linker, not affected by the presence of the trifluoromethlyphenyl group in all the reported DA compounds.
