The photovoltaic properties of dye sensitized solar cells fabricated by employing semiconducting porous films of amorphous ZnSnO3 as photoelectrodes were investigated. ZnSn(OH)6 nanoparticles were synthesized by mixing aqueous solutions of ZnSO4 and Na2SnO3, and amorphous ZnSnO3 films were formed on conductive glass plates by applying a paste containing the nanoparticles followed by heating at various temperatures. The photovoltaic properties of these devices were varied by modifying the heating temperature. The solar cell exhibiting the best performance employed an amorphous, porous ZnSnO3 film heated at 372 °C and was able to convert energy from a xenon light source to electric power. The relationships between the photovoltaic properties and the heating temperature are discussed according to an analysis of the internal resistance of the fabricated solar cells.
