Latest Patents
Doshi's latest patents focus on processes for producing low-cost, high-efficiency silicon solar cells. These processes utilize rapid thermal processing (RTP) to inexpensively produce high-efficiency silicon solar cells. The RTP processes are designed to preserve minority carrier bulk lifetime and allow for selective adjustment of the depth of the diffused regions, including the emitter and back surface field within the silicon substrate. Notably, silicon solar cell efficiencies of 16.9% have been achieved through these innovative methods. The first RTP process involves simultaneously diffusing phosphorus and aluminum into the front and back surfaces of a silicon substrate. Additionally, an in situ controlled cooling procedure is employed to maintain the carrier bulk lifetime and adjust the depth of the diffused regions. The subsequent RTP processes further enhance the efficiency by incorporating simultaneous diffusion, annealing of contacts, and applying a double-layer antireflection/passivation coating.
