Efficient Polycrystalline Silicon Solar Cells with Double Metal Oxide Layers

Abstract

ABSTRACT: Although crystalline silicon solar cells achieve high power conversion efficiency and successfully commercialize, exploring optimization strategies is still necessary. Here, we demonstrate an improved performance of the polycrystalline silicon solar cell by depositing Sb2Ox/CdO double layers on the Si wafer through a low cost route. The metal oxide layers, forming effective heterojunctions, suppress the carrier recombination and reduce the surface reflection. Additionally, heterojunctions of Sb2Ox/CdO/Si enhance the transmission of electrons and holes, simultaneously, a wider response range in the solar spectrum is realized. The power conversion efficiency is improved from 12.6 to 16.7% in a polycrystalline silicon solar cell, with a relative increase by 33%. It is expected that the metal oxides enhanced devices will have tremendous potential in commercial applications.
