New method to fabricate advanced solar cells based on deposited silicon layers

The best silicon solar cells today (efficiency >25%) are made with what are generically called passivated contacts. The most attractive methods are based on depositing a thin layer of polycrystalline silicon (poly-Si) onto the silicon wafer, since they are compatible with high temperature manufacturing steps used by the industry. This project will demonstrate an innovative technology for making high performance poly-Si contact solar cells that is safer, simpler, and more easily scalable to industrial production than the existing methods. The project aims to produce a proof of concept device, thus establishing a solid basis for further collaboration with an already identified industry partner, and to progress a provisional patent to the PCT level.
