The fabrication of dye-sensitized solar cells(DSSC) and a series of technology optimizations are introduced.The influences of the thickness of TiO2 thin film,TiO2 powder treated by HCl,TiO2 electrode treated by TiCl4,and adding light-scattering layer on the efficiency of DSSC are discussed.The optimized thickness of TiO2 electrode is about 12 mm.The experimental results show that the efficiency of DSSC can be improved by HCl treatments,increase of the thickness of TiO2 thin film,adding a light-scattering la...
