Abstract

Chemical properties of n-ZnO/p-CuO heterojunctions for photovoltaic applications

Polycrystalline heterojunctions of n-ZnO and p-CuO were fabricated. The n-ZnO (d~800 nm) was prepared at optimized substrate temperature of 450°C onto the F:SnO2 coated glass substrate by spray pyrolysis technique. The n-ZnO layer was followed by a layer of p-CuO (d~400 nm), which was prepared by vacuum evaporation technique. The structural and morphological properties of individual layers were studied. Band energy diagrams corresponding to these junctions would be needed to understand their properties and these are not available. In the paper, synthesized band energy diagrams of these heterojunctions are purposed based on reported experimental data. The heterojunction (Ag/p-CuO/n-ZnO/F:SnO2) so formed as subjected to annealing at different temperatures such as 100, 200, 300, 400 and 500oC. I-V characteristics of these junctions in dark and under visible light illumination were studied systematically. The heterojunction annealed at 200°C was found to give better electrical response as compared to other studied heterojunction.
