Title: SOLAR CELL AND METHOD FOR PRODUCING SOLAR CELL
Abstract:
This solar cell 10 is provided with: a substrate 20 that is formed of a crystalline semiconductor of a first conductivity type; a first semiconductor layer 21 that is provided on a first region W1 of one main surface of the substrate 20; a second semiconductor layer 22 that is provided on a second region W2 of the one main surface, said second region W2 being different from the first region W1; a first transparent electrode layer 23 that is provided on the first semiconductor layer 21; and a second transparent electrode layer 24 that is provided on the second semiconductor layer 22. The first semiconductor layer 21 contains a first amorphous semiconductor layer 31 of the first conductivity type and a first crystalline semiconductor part 35 that extends from the one main surface toward the first transparent electrode layer 23. The second semiconductor layer 22 contains a second amorphous semiconductor layer 32 of a second conductivity type that is different from the first conductivity type.
