Abstract

The study of dye-sensitized solar cells (DSSCs) based on nano-crystalline 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 DSSCs, the SnO2 nano rots photocurrent is prepared via the hydrothermal method, and characterized by XRD, FESEM, HRTEM and Absorption spectrum. Though analysis the results, the conclusion is shown the better SnO2 nano particles were prepared using the conditions that 0.05mol/L SnCl4 concentration, the reaction time for 4 days, the molar ratio of salt and alkali for 1: 4, a holding temperature of 200øC, and the NaOH as auxiliary agent. The grain diameter of tin oxide is about 7 nanometers, and very uniform circular. SnO2 nano particles has been quite clear, a large number of crystalline phase has been formed, and crystalline phase is very complete. The absorbance in the visible light range shows the very weak absorbance property.
