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 Si 1-x Ge x (0 1-x Ge x 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 Si 1-x Ge x .
