Abstract

A photovoltaic solar cell comprises a light absorbing layer of n-type crystalline silicon. An emitter layer is on the front side of the n-type crystalline silicon. A front passivation layer physically contacts the emitter layer. A front metal contact is on the front passivation layer and contacts the emitter layer. A back layer of wide bandgap semiconductor physically contacts a back side of the n-type crystalline silicon layer. A back metal contact physically contacts the wide bandgap semiconductor layer.
