Abstract

The research work focuses on the application of ZnS Nano particle (NP) phosphors towards the solar cell. ZnS NP phosphors have been successfully synthesized by the chemical co-precipitation method. The ZnS NP is aimed to get over the recombination losses because of incompatibility with spectrum when a low wavelength photons are falling on the multi crystalline-Si-solar cell. The XRD, TEM and UV-Visible measurements were followed out to characterize the dried ZnS NP. The prepared ZnS Nanoparticles (NP) along with poly-methyl-methacrylate (PMMA) were applied on the front surface of the solar cell in three different concentrations ratio of dried ZnS NP into PMMA solution in the ex situ manner. An enhancement in Power conversion efficiency was observed in the ZnS Nanoparticles/PMMA coated solar cell.
