METHOD OF MAKING DEVICE OF THIN-FILM SOLAR CELLS AND SUCH DEVICE OF THIN-FILM SOLAR CELLS Russian patent published in 2019 - IPC H01L31/216 H01L31/224 H01L31/18 

FIELD: electricity.

SUBSTANCE: device of solar cells with a battery of thin-film solar cells on substrate (5) is made so that each solar element is formed by layers, which are lower electrode (6), photoactive layer (7), upper electrode (8) and insulating layer (9). First solar cell and the adjacent second solar cell are separated by first groove (10A) and second groove (11A) parallel to the first groove and located on the first side. First and second grooves are filled with insulating material. First groove extends to the substrate. Second groove extends below the upper electrode into the photoactive layer. Third groove (12) stretching to the lower electrode is located between the first and the second grooves. Fourth groove (13) stretching to the upper electrode is located on the second side from the first groove. Third and fourth grooves are filled with conductive material. Conducting bridge (16) connects the third groove and the fourth groove through the first groove.

EFFECT: invention enables to increase efficiency of photoconversion.
