Abstract
A thin film photovoltaic device having first layer of copper indium selenide, a second layer of cadmium sulfide having a thickness less than 2500 angstroms, and a third layer of conducting wide bandgap semiconductor such as zinc oxide. The transparent third layer allows good transmission of blue light to the junction region while fully depleting the junction area to improve device voltage.
