概要
- 論文の詳細を見る
A GaAs solar cell was successfully transplanted from a GaAs substrate to a Si substrate without degrading the conversion efficiency. The conversion efficiency of the GaAs solar cell bonded to the Si substrate is almost the same as that of the cell grown on a GaAs substrate and is much superior to that of the cell grown on a Si substrate by heteroepitaxy. The GaAs/Si tandem solar cell with the conversion efficiency of 19.4% (top cell: 18.2%, bottom cell: 1.2%) has been demonstrated.
