Abstract
A method for forming an emitter structure on a substrate and emitter structures resulting therefrom is disclosed. In one aspect, a method includes forming, on the substrate, a first layer comprising semiconductor material. The method also includes texturing a surface of the first layer, thereby forming a first emitter region from the first layer, wherein the first emitter region has a first textured surface. The method also includes forming a second emitter region at the first textured surface, the second emitter region having a second textured surface.
