Solarzelle und ihr Herstellungsverfahren |
| 摘要 |
A solar cell comprises a crystalline Si substrate (1) of first type conductivity; a diffusion layer (2) of second type conductivity formed on a first main surface side of said substrate; an Si1-xGex (0 < x </= 1) alloy layer (4, 4a) formed on a second main surface side of said substrate; and an intermediate semiconductor layer (6, 6a) formed in at least part of a region along a boundary between said Si substrate and said Si1-xGex alloy layer. The intermediate semiconductor layer has an intermediate refractive index smaller than that of Si and has an energy bandgap larger than the energy bandgap of said Si1-xGex. <IMAGE> |
