Synthesis and Characterization of SnO2 Nano-Cystalline for Dye Sensitized Solar Cells

Abstract

The study of dye-sensitized solar cells (DSCs) based on nanocrystalline films of high band gap semiconductors is a progressive field of research that is being carried out by scientists in a wide range of laboratories. Of the many semiconductor materials utilized for conversion of solar energy into electricity, SnO2 is a high band gap semiconductor that has been used extensively. However, its efficiency is at a relatively lower level when compared to other semiconductor materials such as TiO2 working under similar circumstances. To improve the conversion efficiency of the DSCs, the SnO2 nanorots photocurrent is prepared via the hydrothermal method, and characterized by XRD, FESEM, BET and Absorption spectrum. Though analysis the results, SnO2 nanocrystalline were successfully synthesized using a hydrothermal method by certainly experimental parameters. The SnO2 nanocrystalline is the rod-shape with length for 100nm and diameter for 5nm as pH=11. the specific surface area is 86.3412m2/g, which lay base for reaching the high conversion efficiency of the DSCs.
