Abstract

In this work, thin film heterojunction solar cells were fabricated by the deposition of p-type gold-doped cobalt oxide layers on n-type silicon substrates using pulsed-laser deposition technique. The effects of the contact material on the photovoltaic characteristics of the fabricated solar cells. It was found that the conversion efficiency was higher than that of the p-CoO/n-Si thin film solar cells, which may attributed to the role of Au-doped CoO layer as a hole collector as well as a barrier for charge recombination.
