The application provides a solar cell, comprising a front electrode, a functional layer and a back electrode, the front electrode is an electrode on the light-receiving surface side, the front electrode includes adjacent high-conductivity regions and low-conductivity regions, or the back electrode includes Adjacent regions of high conductivity and regions of low conductivity. By designing the front electrode and/or the back electrode in sub-regions, and designing the conductivity of one conductive region to be higher than that of the other conductive region, the solar cell can effectively avoid the large-scale lateral uneven transfer of photocurrent. The film square resistance loss improves the photoelectric conversion efficiency of the battery; and according to the different requirements of different regions in different application scenarios, the material can be flexibly selected by region to improve the overall performance of the battery. The present application also provides electronic devices including the solar cells. |
