Optical studies and validation of multidimensional hybrid metamaterial embedded light trapping structure for p-Si/n-ZnO based thin c-Si solar cell

Abstract

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, the author exposed the credibility of ZnO as multidimensional material with dual utility to serve as anti-reflective coating with active material of this heterojunction 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, the author tries to validate the simulated structure in real world by the process of simple fabrication technique, which also offers same optical responses already given by theoretical studies. This investigation also confirms the metamaterial property of the monolayer silica nanoparticles in higher angle of incidence of light, which validates its utility in solar cell where injection of photon is needed throughout the day..
