SOLAR CELL AND METHOD OF MANUFACTURING SOLAR CELL

A solar cell includes: a crystalline semiconductor substrate of a first conductivity type or a second conductivity type; an amorphous layer provided on a principal surface of the substrate; a first-conductivity-type semiconductor layer provided on the amorphous layer; a first high-conduction portion provided inside a first recess portion in the amorphous layer, the first high-conduction portion having a higher conductivity than the amorphous layer, the first high-conduction portion being in contact with the first-conductivity-type semiconductor layer; and a first electrode provided on the first-conductivity-type semiconductor layer. The first-conductivity-type semiconductor layer may be provided in a first region. The solar cell may further include a second-conductivity-type semiconductor layer provided on the amorphous layer in a second region and a second electrode provided on the second-conductivity-type semiconductor layer.
