Dye sensitized solar cell based on TiO₂ sensitized with DN-F01/Ag

Abstract

This research reports the performance of DSSC solar cells that have been fabricated by modification of Ag metal doping with varying concentrations. The sample was deposited by spin coating method and characterized using UV-Vis spectrophotometer to obtain gap energy, FESEM characterization to see sample’s morphology, IPCE, and solar simulator to show performance of DSSC solar cell. The TiO2 / DN-F01 / Ag working electrode layer has a gap energy of 1.95 eV which value is smaller than the pure TiO2 layer and TiO2 / DN-F01 which value is 3.15 eV and 2.3 eV respectively. The results show the greatest efficiency found in Ag doped dye solar cell samples with Ag mass of 0.0172 gr. This result was influenced by Ag metal which has good light absorption ability, extends TiO2 response to visible light, and charge recombination.
