Fabrication and optoelectrical properties of IZO/Cu 2O heterostructure solar cells by thermal oxidation

Abstract

Indium zinc oxide (IZO)/cupper oxide (Cu 2O) is a nontoxic nature and an attractive all-oxide candidate for low-cost photovoltaic (PV) applications. The present paper reports on the fabrication of IZO/Cu 2O heterostructure solar cells which the Cu 2O layers were prepared by oxidation of Cu thin films deposited on glass substrate. The measured parameters of cells were the short-circuit current (I sc), the open-circuit voltage (V oc), the maximum output power (P m), the fill factor (FF), and the efficiency (), which had values of 0.11mA, 0.136V, 5.05W, 0.338, and 0.56, respectively, under AM 1.5 illumination.
