SOLAR CELL AND METHOD FOR MANUFACTURING SOLAR CELL

Provided is a solar cell capable of improving performance. A solar cell (1) is a back surface junction type solar cell, and is provided with a semiconductor substrate (11), first semiconductor layers (25, 23) laminated in a first region (7) that is a part of the back surface side of the semiconductor substrate (11), and second semiconductor layers (35, 33) laminated in a second region (8) that is another part of the back surface side of the semiconductor substrate (11). First semiconductor layers (25, 23) are present in a portion between the semiconductor substrate (11) and the second semiconductor layers (35, 33), and the first semiconductor layers (25, 23) have a sea shape in a sea-island structure. 本发明提供能够提高性能的太阳能电池。太阳能电池(1)是背面接合型的太阳能电池，具备半导体基板(11)、在作为半导体基板(11)的背面侧的一部分的第1区域(7)层叠的第1半导体层(25、23)以及在作为半导体基板(11)的背面侧的另一部分的第2区域(8)层叠的第2半导体层(35、33)，在第2区域(8)中，在半导体基板(11)与第2半导体层(35、33)之间的一部分存在第1半导体层(25、23)，第1半导体层(25、23)是海岛构造中的海形状。
