Abstract
A photovoltaic cell can include a heterojunction between semiconductor layers. The first semiconductor layer can include a III-V compound semiconductor, the first semiconductor layer positioned over a transparent conductive layer. A second semiconductor layer can include a II-VI compound semiconductor, the second semiconductor layer positioned between the first semiconductor layer and a back metal contact.
