제목 Alkynyl-Substituted D-π-A Structural Zn(II)-Porphyrin Sensitizers Containing Various Donor Units for Dye-Sensitized Solar Cells
초록 Dye-sensitized solar cells(DSSCs) have been regarded as next-generation photovoltaics for providing electricity at lower expense and more versatility. Porphyrins are one of the most widely studied sensitizers for DSSCs because of their absorbing strong Soret bands and Q bands. New alkynyl-substituted porphyrin sensitizers were designed and synthesized with the combination of the bulky triphenylamine(TPA) derivatives as the donor, such as dihexyloxy-substituted TPA and bis(dihexyloxy)phenyl-substituted TPA moiety, double alkynyl-substituted porphyrin as the π-bridge and benzothiadiazole(BTD)-based derivative as the acceptor. Porphyrin with doubly alkynyl substituent was introduced as the π-bridge unit for red-shifting the Soret and Q bands with respect to single alkynyl-substituted porphyrin. In this study, their structure-performance relationships were investigated with the influence of the various donor moieties on the photophysical, electrochemical and photovoltaic properties.
