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.
