Abstract
A device and method of improving efficiency of a thin film solar cell by providing a back reflector between a back electrode layer and an absorber layer. Back reflector reflects sunlight photons back into the absorber layer to generate additional electrical energy. The device is a photovoltaic device comprising a substrate, a back electrode layer, a back reflector, an absorber layer, a buffer layer, and a front contact layer. The back reflector is formed as a plurality of parallel lines.
