  • Radiation resistant passivation of silicon solar cells
    Patent number: 5030295
    Abstract: The interface of a silicon oxide passivation layer and a silicon substrate in a silicon solar cell is stabilized by covering the silicon oxide passivation layer with a layer of undoped or phosphorus doped polycrystalline silicon. A second layer of silicon oxide is formed by deposition on the surface of the phosphorus doped polycrystalline and enhances the anti-reflection characteristics of the composite structure.
