Data for: Extraction of ZnO thin film parameters for modeling a ZnO/Si solar cell

• Fabrication of ZnO film by sol–gel using zinc acetate decomposition • Extraction of the optical parameters to be used in modeling a ZnO/p-Si solar. • This is to elucidate the solar cell weak performance • Defects in the ZnO bulk and the surface recombination velocity in the ZnO/p-Si interface were responsible. • The simulation led to comparable values between simulation and measurement of J-V characteristics.
