PHOTOVOLTAIC DEVICE AND METHOD OF MANUFACTURING PHOTOVOLTAIC DEVICES

摘要

A photovoltaic device includes a supporting layer, a semiconductor layer stack, and a conductive and light transmissive layer. The supporting layer Is proximate to a bottom surface of the device. The semiconductor layer stack inc ludes first and second semiconductor sub-layers, with the second sub- layer having a crystalline fraction of at least approximately 85%. A conductive and light transmissive layer between the supporting layer and the semiconductor layer stack, where an Ohmic contact exists between the first semiconductor sub-layer and the conductive and Sight transmissive layer.
