Abstract: In the solar cell system electricity did not be produced if there was no dye because there would be no electron flow in the conduction band, where the dye on the surface of the thin layer of TiO2 acted as an electron injector in the conduction band. The number of dyes adsorbed on TiO2 was influenced by several factors, including dye concentration, immersion time during the adsorption process, and thickness of the TiO2 layer. The performance of DSSC was studied by measuring currents with voltage variations. The best conditions for the dye adsorption process of mangosteen peel extract on TiO2 semiconductors were obtained at a concentration of 25%, immersion time of 120 minutes, and thickness of TiO2 of 5 times of coating. The best efficiency was also obtained at a concentration of 25%, immersion time 120 minutes, and thickness of TiO2 of 5 times coating.
