Abstract: In this work, a new metal-mediated self-assembly strategy for organizing horizontally anchored porphyrin (ZnPA) and upper antennal porphyrin (ZnPw) on the nanostructured TiO2 electrode surfaces has been developed by a ZnPw-ZnPA assembly approach. Further, the horizontally anchored porphyrins are adsorbed on the semiconducting TiO2 electrode surfaces by the carboxylic groups, and the photovoltaic performances in solar cells are measured under an irradiance of 100 mW/cm2 AM 1.5G solar simulator. With single anchored porphyrin (ZnPA, η=0.61%) as reference, the assembly device ZnPw-ZnPA had better photoelectric conversion efficiency (η) of 1.08%. Its η is 1.8 times that of single anchored porphyrin.
