Abstract
A solar cell and a photovoltaic module including the same are provided. The solar cell includes a substrate having a first surface and a second surface opposite to each other; a first passivation stack disposed on the first surface and including a first oxygen-rich dielectric layer, a first silicon-rich dielectric layer, a second oxygen-rich dielectric layer, and a second silicon-rich dielectric layer that are sequentially disposed in a direction away from the first surface, wherein an atomic fraction of oxygen in the first oxygen-rich dielectric layer is less than an atomic fraction of oxygen in the second oxygen-rich dielectric layer; a tunneling oxide layer disposed on the second surface; a doped conductive layer disposed on a surface of the tunneling oxide layer; and a second passivation layer disposed on a surface of the doped conductive layer.
