This backside bonded solar cell has a first conductivity type contact region and a second conductivity type contact region on the principal surface on the opposite side from the light incidence surface, the first conductivity type contact region being a region of homojunction between a crystalline base layer and a crystalline first conductivity type layer, and the second conductivity type contact region being a region of heterojunction between a base layer, an amorphous i type layer, and a second conductivity type layer. |
