METHOD FOR PRODUCING AN EMITTER STRUCTURE AND EMITTER STRUCTURES RESULTING THEREFROM

摘要

A method is described for forming an emitter structure on a substrate. The method comprises forming, on the substrate, a first layer comprising semiconductor material; texturing a surface of the first layer, thereby forming a first emitter region from the first layer, the first emitter region having a first textured surface; and forming a second emitter region at the first textured surface, the second emitter region having a second textured surface.
