Solar cell and production method thereof, photovoltaic module

Abstract

Embodiments of the present disclosure provide a solar cell and a production method thereof, and a photovoltaic module. The solar cell includes: a substrate; a tunnel dielectric layer, located on a surface of the substrate; a doped conductive layer, located on a surface of the tunnel dielectric layer away from the substrate, the doped conductive layer includes a doping element of a same type as a doping element of the substrate, and a plurality of sets of heavily doped areas, the sets includes first heavily doped areas and second heavily doped areas extending in a first direction and arranged at intervals in a second direction; and a plurality of electrodes arranged at intervals, the electrodes extend in the second direction and correspond to the sets, and the electrodes contact with at least part of each sets. The present disclosure can improve photoelectric conversion efficiency of the solar cell.
