Lightweight, Thin-Film Si Heterojunction Solar Cells
Progress in Photovoltaics
This approach to a thin-film Si solar cell combines theoretical analysis, growth of thin-film crystalline Si (c-Si) and deposition of amorphous Si (a-Si:H) to form the heterojunction. The PC-1D model predicts a potential efficiency of >16% for an Si thickness of 10 μm. Liquid phase growth (LPG) of the base-layer c-Si gave a carrier mobility of 100 cm2 V−1 s−1 and a lifetime of 8 μs. Microwave electron cyclotron resonance (MECR) deposition of a-Si:H onto a c-Si wafer gives over 10% photovoltaic conversion efficiency. Work continues to combine MECR with LPG to give a thin-film Si solar cell.
