Zinc phosphide-zinc oxide heterojunction solar cells

Authors:

Abstract
The photovoltaic properties of p‐Zn3P2/n‐ZnO heterojunction solar cells prepared by sputter deposition of ZnO on Zn3P2 substrates are reported. An active‐area power conversion efficiency of ∼2% has been obtained. The experimental results are discussed on the basis of an interface recombination model. The interface plays a significant role in determining the performance of the device.
