摘　　要：Bipyridylporphyrin derivatives possessing a porphyrin moiety as the electron donor and bipyridyl moiety as the electron-acceptor were designed and synthesized for dye-sensitized solar cells （DSSCs）. The photo- physical and electrochemical properties were investigated by absorption spectrometry and cyclic voltam- metry. Density functional theory （DFT） was employed to study electron distribution. From the photovoltaic performance measurements, a maximum conversion efficiency （η） of 0.38% was achieved based on the bipyridylporphyrin ruthenium dye A7 （Jsc = 1.33 mA/cm^2, Voc = 0.45 V, FF = 0.64） under 1,5 irradiation （100 mW/cm^2）.Bipyridylporphyrin derivatives possessing a porphyrin moiety as the electron donor and bipyridyl moiety as the electron-acceptor were designed and synthesized for dye-sensitized solar cells （DSSCs）.
