Abstract

Titanium dioxide (TiO2) nano-particles and films were prepared by the sol-gel method and zinc oxide (ZnO) films were synthesized by rf sputtering method. The results of investigation of un-coated and TiO2 and ZnO nano-particle films coated monocrystalline silicon solar cells are presented. The investigation of current – voltage characteristics to determine electrical properties of monocrystalline silicon solar cells was carried out after annealing the samples at different temperatures. The fill factor varied with the annealing temperature and nano-particle films deposited on the solar cell. The light absorption is affected by the morphological changes on the surface of the solar cell. The use of metal oxide nano-particles on the surface of silicon solar cells enhanced the performance of solar cell.
