摘　　要：制备了ZnTSSP／TiO2、GaTSPC／TiO2和共吸附ZnTSSP、GaTSPc／TiO2电极，并研究了它们的光电特性．结果表明，共吸附的ZnTSSP、GaTSPc／TiO2电极不仅拓宽了光电响应范围，而且提高了光电转换效率，特别是提高了GaTSPc的光电转换效率．其原因可能是GaTSPc的聚集体没有敏化作用，而卟啉和酞菁分子与TiO2共吸附可以减少GaTSPc的聚集。ZnTSPP/TiO2, GaTSPc/TiO2 and co-adsorbed ZnTSPP, GaTSPc/TiO, electrodes have been prepared- The spectroscopic and photovoltaic properties of these electrodes have been studied. The results indicate that the electrode co-adsorbed with porphyrin and phthalocyanlne can not only expend the spectra of photo-current action, but also enhance the efficiency of the incidentanphot0n-current-convers (IPCE), especially enhance the efficiency of IPCE of GaTSPc. This is because the aggregates of GaTSPc have no the sensitization effect, and the aggregates of GaTSPc decrease by co-adsorption of porphyrin and phthalocyanine, so the sensitization effect ability of phthalocyanine is increased signification.
