摘要

How to improve the conversion efficiency and the stability ofdye-sensitized solar cells (DSSCs) are two major problems. Furthermore, reduction of the manufacturing cost of DSSCs andlarge-scale manufacture are also very important factors. As a rawmaterial, commercial P25 would be used for large-scale manufactureof TiO2paste with simple preparation procedure. However, thereare several drawbacks for P25 such as the low surface area of P25powder and the poor connectivity among particles in film usingtradition P25 paste without modification. In this paper, weintroduced a simple modified method by adding high surface areaanatase TiO2into pure P25 paste. The photoelectric conversionperformances of DSSCs based on these photo-electrodes were tested. The results show that the open-circuit voltage, the fill factorand the energy conversion efficiency of the modified electrodewere increased. It is found that the modified P25 films have fastelectron transportation and a slow charge recombination. Weconclude that through adding the anatase TiO2nanoparticles to theP25 paste with high surface area, it can not only improve theparticles connectivity among inside the films, but also enhancethe efficiency of DSSCs.
