Title:
PEROVSKITE/SILICON HETEROJUNCTION TANDEM SOLAR CELL AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/185464
Kind Code:
A1
Abstract:
The present invention relates to the technical field of solar cells, and specifically to a perovskite/silicon heterojunction tandem solar cell and a production method therefor. The solar cell comprises a silicon-based sub-cell and a perovskite sub-cell tandemly arranged on the silicon-based sub-cell. An intermediate layer or a recombination junction formed by a p-type heavily doped amorphous silicon layer and an n-type heavily doped amorphous silicon layer is provided between the silicon-based sub-cell and the perovskite sub-cell. According to the present invention, the p-type heavily doped amorphous silicon layer and the n-type heavily doped amorphous silicon layer are used as a carrier recombination junction, such that the production and device costs are greatly reduced, and in addition, the photocurrent density and conversion efficiency of the tandem cell can be improved.
