Title:
SOLAR CELL AND METHOD FOR MANUFACTURING SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2021/193413
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a solar cell that can be easily manufactured. The solar cell (1) according to an embodiment of the present invention is provided with: a semiconductor substrate (11); a first semiconductor layer (21) and a second semiconductor layer (31) formed in a strip shape extending in a first direction on the reverse surface side of the semiconductor substrate (11) and alternately laminated in a second direction intersecting the first direction; transparent electrodes (31, 32) laminated in a strip shape extending in a first direction on the reverse surface side of the center part of the first semiconductor layer (21) and on the reverse surface side of the center part, with respect to the second direction, of the second semiconductor layer (31); base electrodes (41, 42) laminated, so as to extend in the first direction, on the reverse surface side of the center part of the transparent electrodes (31, 32) with respect to the second direction; an insulating member having main insulating parts (53, 55) laminated across the reverse surface side of strip-shaped side edge regions, extending in the first direction, on both sides of the transparent electrodes (31, 32) with respect to the second direction and the reverse surface side of square insulating regions, intermittent in the first direction, of the base electrodes (41, 42), and auxiliary insulating parts (54, 56) laminated, so as to extend in the first direction, on the reverse surface side of the center part, with respect to the second direction, of connection regions complementary to the insulating regions of the base electrodes (41, 42); and cap electrodes (61, 62) laminated on the reverse surface side of the connection regions of the base electrodes (41, 42) so as to cover the auxiliary insulating parts (54, 56).
