(a) Schematic presentation of the photovoltaic configuration with co-doped CuCrO2 as the p-type layer and AZO as the n-type UV absorber, all deposited on quartz substrate with Ag/Au ohmic contacts. (b) Schematic presentation of the photoconductive configuration that is composed of an AZO layer with Ag/Au contacts deposited on quartz substrate. [The schematics are created using Microsoft office PowerPoint 2019 software] (c) Band structure diagram of the photovoltaic configuration and (d) photoconductive configuration plotted with bandgaps of 3.05 eV46 and 3.2 eV47 and electron affinities15 of 3 and 4 eV, respectively for CuCrO2 and ZnO layers.
