Photogenerated Current By Two-Step Photon Excitation in ZnTeO Intermediate Band Solar Cells with n-ZnO Window Layer

Abstract

We present the results of systematic experimental studies on ZnTeO intermediate band solar cells (IBSCs) with a n-ZnO window layer. In order to understand photovoltaic (PV) activities of ZnTeO IBSCs, we first describe PV properties of ZnO/ZnTe solar cells without the intermediate band (IB). The improved efficiency of 1.38% is demonstrated by using a n<sup… (More)
