Title:
THIN-FILM SOLAR CELL AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/071233
Kind Code:
A1
Abstract:
Disclosed in embodiments of the present application are a thin-film solar cell and a manufacturing method therefor. The thin-film solar cell comprises: N transparent conductive layers located on a first surface of a substrate, N≥2; a sub-cell laminated structure and a first electrode layer which are located on the surface of a first area of the transparent conductive layer to form N sub-cells, wherein the first electrode layer on the surface of a first area of the i-th transparent conductive layer is connected to a first area of the (i+1)-th transparent conductive layer; and N bypass diodes, wherein the positive electrode of the i-th bypass diode is connected to the negative electrode of the i-th sub-cell, and the negative electrode thereof is connected to the positive electrode of the i-th sub-cell; the positive electrode of the N-th bypass diode is connected to the negative electrode of the N-th sub-cell, and the negative electrode thereof is connected to the positive electrode of the N-th sub-cell, that is, the bypass diodes are reversely connected in parallel to the N sub-cells respectively, such that the problem that the overall current of the thin-film solar cell is reduced due to defects or shielding caused by one or a plurality of sub-cells is solved.
