Abstract
Provided are a solar cell and a photovoltaic module. The solar cell includes: an N-type silicon substrate, where the N-type silicon substrate has a front surface and a rear surface opposite to the front surface; a passivation layer that contains an aluminum oxide material and that is located on the front surface; a first antireflection layer, a second antireflection layer, and a third antireflection layer that are located on a side of the passivation layer away from the substrate and stacked in a direction in which the substrate points to the passivation layer, where the first antireflection layer contains a silicon nitride material, the second antireflection layer contains a silicon oxynitride material; and the third antireflection layer contains a silicon oxide material; a tunneling dielectric layer located on the rear surface; and a doped conductive layer located on the tunneling dielectric layer.
