Abstract: A method for manufacturing a solar cell, including: a step for irradiating a semiconductor substrate to cause the surface to become amorphous and to form an intrinsic amorphous layer, a first conductivity-type layer, and a second conductivity-type layer; and a step for introducing hydrogen into the intrinsic amorphous layer, the first conductivity-type layer, and the second conductivity-type layer.

Abstract: A solar cell is equipped with: a wafer; an n-type laminated body that is provided on the first main surface side of the wafer; and a p-type laminated body, which is provided on the first main surface side of the wafer such that the p-type laminated body is adjacent to the n-type laminated body in the X direction, and which extends in the Y direction. The wafer has: a lightly doped region that is doped to be n type; and a plurality of first main surface-side highly doped regions, which have an n-type dopant concentration that is higher than that of the lightly doped region, and which are provided between the lightly doped region and the p-type laminated body. The first main surface-side highly doped regions are discretely provided at intervals in the Y direction.

Abstract: In an embodiment, photoelectric conversion units (10) each include a package (12) accommodating a photoelectric conversion device (11). The package (12) has a front surface (12a) having a window (13); and a side surface (12c). The package (12) includes a first coupling portion (14) protruding from the side surface (12c) in a first direction X parallel to a light incident surface (11a) of the photoelectric conversion device (11), and a second coupling portion (15) recessed from the side surface (12c) in the first direction X. The first coupling portion (14) includes a first terminal (16) electrically connected with the photoelectric conversion device (11), and the second coupling portion (15) includes a second terminal (17) electrically connected with the photoelectric conversion device (11). The first coupling portion (14) and the second coupling portion (15) have shapes and sizes matching each other, and are coupled with each other by fitting.
