Abstract
Heterojunction devices and associated methods of making and using are provided. In one aspect, for example, a heterojunction photovoltaic device can include a crystalline semiconductor layer, a first doped semiconductor layer coupled to the crystalline semiconductor layer, and a second doped semiconductor layer coupled to the crystalline semiconductor layer opposite the first doped semiconductor layer. The first and second doped semiconductor layers form junctions with the semiconductor layer. The device can further include a laser processed semiconductor region coupled to the crystalline semiconductor layer.
