Abstract: This application provides a solar cell, including a front electrode, a functional layer, and a back electrode. The front electrode is an electrode on a side of an illuminated surface. The front electrode includes a high-conductivity region and a low-conductivity region that are adjacent to each other, or the back electrode includes a high-conductivity region and a low-conductivity region that are adjacent to each other. The front electrode and/or the back electrode may be designed to be separated by region, and conductivity of one conductive region is designed to be higher than conductivity of the other conductive region. This can effectively avoid a film rectangular resistance loss caused by large-scale non-uniform lateral transfer of a photocurrent, and improve photoelectric conversion efficiency of the cell. In addition, cell comprehensive performance can be improved by flexibly selecting materials based on different requirements of different regions in different application scenarios.

Abstract: The technology of this application relates to a cell assembly and a method for preparing a cell assembly. The cell assembly includes a first subcell, a second subcell adjacent to the first subcell, and a bottom electrode. Both the first subcell and the second subcell include a P-type layer and an N-type layer, and a light-harvesting layer located between the P-type layer and the N-type layer. The P-type layer of the first subcell is connected to the N-type layer of the second subcell by using the bottom electrode. A connection manner between subcells is provided. Compared with a current manner in which P1, P2, and P3 gaps are formed between subcells through cutting to implement interconnection, geometrical optical loss brought by interconnection between the subcells can be reduced.
