Abstract
A photovoltaic device includes an absorber layer having a back contact formed on the absorber layer, the back contact having an exposed surface free from a substrate. It further includes a top contact formed in contact with a transparent conductive layer opposite the back contact and a stressor layer forming a superstrate on the absorber layer opposite the back contact.
