Over the past few decades, a large number of studies have focused on metal oxide semiconductors materials for their potential applications to solar energy conversion. Among the range of semiconductors available, TiO2-based materials are most popular and considerable progress has been achieved. Recently, other semiconducting materials except of TiO2 have been reported to have light-absorbing capabilities in the UV-visible regions. In this study, SnO2-nanosized particle was synthesized and its structural and size analysis was characterized though X-ray diffraction and transmission electron microscopy. The multi-layered SnO2 films were used for application as an anode electrode in dye-sensitized solar cells. Compared to the p-25 TiO2-DSSC, the application of SnO2-layered anode films to the DSSCs rather decreased the energy conversion efficiency considerably; the efficiency for the SnO2-triple layered-DSSC was approximately 1.375%. |
