Back contact solar cell and method for manufacturing same and photovoltaic module

Abstract

The present application discloses a back contact solar cell and a photovoltaic module. An example back contact solar cell includes a semiconductor substrate, a first doped semiconductor layer, a second doped semiconductor layer, and a dielectric layer. The first doped semiconductor layer is disposed on a first region and a third region. The second doped semiconductor layer is disposed on a second region and the third region. A doping type of the first doped semiconductor layer is opposite to that of the second doped semiconductor layer. On the third region, the first doped semiconductor layer and the second doped semiconductor layer overlap in a thickness direction of the semiconductor substrate to form a stacked structure. The dielectric layer is disposed at least between the first doped semiconductor layer and the second doped semiconductor layer. A leakage path is disposed in the dielectric layer.
