Abstract
A solar cell and a photovoltaic module. The solar cell includes: a substrate including a first surface; a tunneling oxide layer covering the first surface; a doped conductive layer covering a surface of the tunneling oxide layer away from the substrate; an intrinsic polycrystalline silicon layer formed on one side of the doped conductive layer away from the tunneling oxide layer; and a plurality of first electrodes arranged on one side of the intrinsic polycrystalline silicon layer away from the doped conductive layer and electrically connected to the doped conductive layer. At least a portion of the first electrode is located in the intrinsic polycrystalline silicon layer, and a gap is defined between a top end of the first electrode and the substrate.
