Title:
SOLAR CELL SUB MODULE AND METHOD FOR MANUFACTURING SOLAR CELL SUB MODULE
Document Type and Number:
WIPO Patent Application WO/2023/190570
Kind Code:
A1
Abstract:
A solar cell sub module 1 with high photoelectric conversion efficiency according to one aspect of the present invention comprises a substrate 11, a first electrode layer 12, a first charge transport layer 13, a photoelectric conversion layer 14, a second charge transport layer 15, a second electrode layer 16, and an inorganic insulating layer 17 which are stacked in this order. The solar cell sub module has: a first separation groove 21 formed so as to cut the first electrode layer 12; a second separation groove 22 formed so as to cut the first charge transport layer 13, the photoelectric conversion layer 14, and the second charge transport layer 15; and a third separation groove 23 formed so as to cut the first charge transport layer 13, the photoelectric conversion layer 14, the second charge transport layer 15, and the second electrode layer 16. The inner surface of the first separation groove 21 is covered by the first charge transport layer 13, the inner surface of the second separation groove 22 is covered by the second electrode layer 16, and the inner surface of the third separation groove 23 is covered by the inorganic insulating layer 17.
