Abstract
The present disclosure provides a solar cell. The solar cell includes a substrate, where the substrate has a front surface and a rear surface, the rear surface includes a textured region and a flat region, a doped surface field is formed in the textured region of the substrate; a tunneling dielectric layer, where the tunneling dielectric layer is located on the flat region; a doped conductive layer, where the doped conductive layer is located on the tunnelling dielectric layer, the doped conductive layer has doping elements, and the doped conductive layer has the same type of the doping elements with the doped surface field; a rear electrode, where a part of a bottom surface of the rear electrode is located in the doped conductive layer and the part of the bottom surface of the rear electrode is in contact with the doped surface field.
