Abstract
A photovoltaic device on a non-semiconductor substrate is disclosed. The device comprises two semiconductor layers forming an active region; at least one of the semiconductor layers is formed by a high-purity plasma spray process; optional layers include one or more barrier layers, a cap layer, a conductive and/or metallization layer, an anti-reflection layer, and distributed Bragg reflector. The device may comprise multiple active regions.
Claims13
A photovoltaic device structure for converting incident radiation into electrical energy comprising:
- a substrate;
- a first barrier layer comprising vias through the first barrier layer in a predetermined pattern;
- and
- a first semiconductor layer of first conductivity wherein the first barrier layer separates the first semiconductor layer from the substrate and the vias provide an electrical connection between the first semiconductor layer and the substrate.
