Abstract
The fabrication of low-cost solar cells for economic conversion of sunlight into electricity requires the use low-grade polycrystalline silicon instead of the semiconductor-grade single crystal used at present. It has been demonstrated that the application of a nonsingle crystalline silicon with controlled size and structure of the indicidual grains lead to solar cells with an acceptable high efficiency. With a solar cell processing optimized in respect to this material large area solar cells of 10 cm×10 cm can be realized exhibiting efficiencies exceeding 10%. Test structures of 2 cm×2 cm area have been realized with an efficiency up to 14%, which is comparable to single crystal solar cells.
