Progress in Silicon-based Thin Film Solar Cells

Silicon-based thin film solar cells include hydrogenerated amorphous silicon solar cells, hydrogenerated microcrystalline silicon solar cells,polycrystalline silicon thin film solar cells and siliconbased thin film tandem solar cells.The microstructure,optical and electrical properties of silicon-based thin film materials and devices are investigated.The performance optimization design of silicon-based thin film cells is discussed.The recent advances such as the antireflection coating of a-Si:H solar cells, the u-Si:H material with nanometer grains,the novel structure of tandem solar cells with interlayers and the high stability polycrystalline silicon thin film CSG solar cells are presented.
