Design and Validation of Multidimensional Hybrid Metamaterial Embedded Light Trapping Structure for p-Si/n-ZnO Based Thin c-Si Solar Cell

Abstract

This paper deals with one competent light trapping structure of metamaterials embedded p-Si/n-ZnO based thin solar cell assisted by different simulation studies. Through this article, author exposed the credibility of ZnO as multidimensional material with dual utility to serve as anti reflective coating with active material of this hetero-junction solar cell. Additionally, dielectric metamaterial like silica nanoparticles on top of the structure enhanced the photon cultivation efficiency of the device. Further through this work try to validate the simulated structure in real world by the process of simple fabrication technique which also offer same optical responses already given by theoretical studies. This investigation also confirms the metamaterial property of the monolayer silica nanopartcles in higher angle of incidence of light which validate its utility in solar cell where injection of photon was needed throughout the day. During the analysis of electric field and reflectance profiles generated by mentioned light trapping structure, it is very recognizable that, in future this type of hybrid structure which is combination of semiconductor with metamaterials will make solar cell more efficient and cost effective.
