摘要
Low cost triple junction solar cells, which are very important for the development of industry, have been studied in this paper. Based on the amorphous silicon/amorphous silicon tandem solar cells realized in industry using completely single chamber deposition technique, amorphous silicon /amorphous silicon/microcrystalline silicon (a-Si:H/a-Si:H/μc-Si:H) triple junction solar cells with 9.13% initial conversion efficiency have been fabricated by changing deposition condition for n/p tunnel junction treatments which include H plasma treatment, variation of μc-Si:H n layer deposition conditions, and variation of p layer thickness in a single chamber developed by us. It has proved that amorphous silicon thin film solar cell now in industry can be progressed by introducing single chamber microcrystalline silicon thin film solar cells technique.
