Efficiency enhancement of Solar Cell by introduction of Cerium Oxide along with Silicon Nitride

摘要

In this paper we have carried out the comparative simulations study of n type c-Si Solar Cell with SiNx and SiNx+CeO_2 layers separately by PC1D simulation software. The motivation of this paper is to determine the optimum condition when Solar Cell yields more efficiency by using SiNx+CeO_2 layer rather than only SiNx layer respectively on the front side of the Solar Cell. For these purpose the simulations have been done by changing the thickness and refractive index of CeO_2 layer. By the observation of simulation's data i.e. reflectance versus wavelength, Quantum Efficiency versus wavelength, and current density versus voltage curves, it has been endeavored to determine the optimum condition when the Solar Cell with SiNx+CeO2 layer yield the maximum possible efficiency. In this paper the efficiency of Si+SiNx+CeO2 combination has been found as 17.34% whereas the Si+SiNx combination gives the efficiency about 16.91%.
