Effect of Controlling Concentration on the Properties of SnO₂ Nanocystalline 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. To improve the conversion efficiency of the DSCs, the SnO₂ nanorots photocurrent, the effect of controlling concentration on the properties of SnO₂ nanocrystalline were investigated via the hydrothermal method, and characterized by XRD, HRTEM, BET and Absorption spectrum. Though analysis the results, the conclusion is shown the pure SnO₂ is preparation, the prepared SnO₂ nanocrystalline under 0.05mol/L shows the particle-shape crystalline, the surface area of SnO₂ nanocrystalline is 102.1683m²/g. The prepared SnO₂ nanocrystalline under 1mol/L the fiber-shape crystalline, the surface area of SnO₂ nanocrystalline is 79.7591m²/g. The absorbance of SnO₂ nanocrystalline shows the strong absorption in the ultraviolet ray range, the absorbance of synthesized SnO₂ nanocrystalline under the concentration of SnCl₄ solution for 1mol/L shows the higher value.
