Abstract
This paper explores the effect of sintering temperature of TiO2 films on the efficiency of dye sensitized solar cells. Structural studies on the specimens were carried out using XRD which shows anatase phase with increasing crystallite size 29, 36, 43 nm with sintering temperature of 450, 550 and 650°C respectively. The microstructure was studied by SEM analysis which shows agglomeration of TiO2 particles for film sintered at 650°C. The sintered films were characterized by FTIR studies and are reported. The maximum efficiency of DSSCs fabricated by using TiO2 sintered at 450, 550 and 650°C were found to be 1.3, 0.85 and 0.09 % respectively.
