Abstract:
1. A method to form a photovoltaic assembly, the method comprising: doping a first surface of a semiconductor donor body by diffusion doping to a first conductivity type to form a doped first surface; defining a cleave plane in the semiconductor donor body; affixing the doped first surface to a receiver element; cleaving a lamina from the semiconductor donor body at the cleave plane, wherein the lamina remains affixed to the receiver element, wherein a second surface of the lamina is created by the cleaving step; depositing amorphous silicon directly on the second surface, wherein at least a part of the amorphous silicon is heavily doped; and fabricating a photovoltaic cell with an emitter and a base, wherein the heavily doped amorphous silicon comprises the emitter of the photovoltaic cell, and the lamina comprises the base of the photovoltaic cell.
