Abstract
Embodiments of the present disclosure provide a solar cell and a photovoltaic module. The solar cell includes: a substrate having a front surface and a rear surface, a first doped polycrystalline silicon layer doped with N-type dopant ions and disposed over the front surface or over the rear surface, and a second doped polycrystalline silicon layer doped with P-type dopant ions and disposed over the rear surface. A surface of the first doped polycrystalline silicon layer away from the substrate has a plurality of first protrusion structures. A surface of the second doped polycrystalline silicon layer away from the substrate has a plurality of second protrusion structures. An average thickness of the first protrusion structures is greater than an average thickness of the second protrusion structures, and a thickness of the first doped polycrystalline silicon layer is not greater than a thickness of the second doped polycrystalline silicon layer.
