Solar cell and method for preparing the same, tandem solar cell, and photovoltaic module

Abstract

Disclosed are a solar cell, a tandem solar cell, and a photovoltaic module. The solar cell includes a substrate, a doped semiconductor layer, a passivation layer and a plurality of electrodes. The substrate is provided with textured structures on a portion of a surface of the substrate. The doped semiconductor layer is disposed on the substrate. The solar cell further includes holes extending through the doped semiconductor layer, and corresponding to the textured structures, respectively, and a bottom of a respective hole exposes at least a portion of a corresponding textured structure. The passivation layer is formed over a surface of the doped semiconductor layer away from the substrate, fills the holes. The plurality of electrodes are arranged along a first direction, pass through the passivation layer and are in electrical contact with the doped semiconductor layer.
