Solar cell and production method of the same

Abstract

Embodiments of the present disclosure relate to the field of photovoltaic technology, and provide a solar cell and a method for producing the same. The solar cell includes: a substrate including a front surface and a back surface opposite to each other, front electrodes formed on the front surface, at least one doped structure formed on the back surface and having doping ions of a first type, a tunneling layer covering at least portions of the back surface and a surface of the at least one doped structure away from the substrate, a doped conductive layer formed over a surface of the tunneling layer away from the substrate and having doping ions of a second type, and back electrodes formed on a side of the doped conductive layer away from the substrate and in electrical connection with the doped conductive layer.
