Influence of Substrate Properties on the Efficiency of Dye Sensitized Solar Cells

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.
