Abstract
The application of metallic nanoparticles on heterjunction (HJ) silicon solar cell was investigated in recent years. In this paper, the gold (Au) nanoparticles (NPs) colloidal solution diluted with different concentration was coated on the surface of crystalline silicon (c-Si) and embedded in p-type amorphous silicon (a-Si) emitter layer and indium tin oxide (ITO) in order to enhance the light trapping of the HJ silicon solar cell. The density of Au NPs is very important to improve the performances of the HJ silicon solar cell. At the optimum process parameters, HJ silicon solar cell improved the power conversion efficiency and the short-circuit current (Jsc) by Au NPs coated on c-Si surface.
