Abstract
A solar cell is provided, 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. According to the application, a film rectangular resistance loss caused by large-scale non-uniform lateral transfer of a photocurrent is avoided, thereby improving photoelectric conversion efficiency of the cell, and improving the cell comprehensive performance by flexibly selecting materials based on different requirements of different regions in different application scenarios.
