Wurtzite CoO: a direct band gap oxide suitable for a photovoltaic absorber

Author affiliations

Abstract

A direct band gap of 1.6 eV has been identified in wurtzite CoO thin films, which matches the required value to achieve a theoretically high conversion efficiency solar cell. Its p-type conduction has been determined and an intense sub-gap absorption between 0.7 and 1.1 eV has been observed.
