Abstract
A solar cell, a manufacturing method therefor, and a photovoltaic module are provided. The solar cell includes a substrate having a front surface and a rear surface, a passivation stack disposed on the front surface, and a tunneling oxide layer and a doped conductive layer disposed on the rear surface. The passivation stack includes an oxygen-containing dielectric layer, a first passivation layer and a second passivation layer. The first passivation layer includes a first interface adjacent to the oxygen-containing dielectric layer and a second interface adjacent to the second passivation layer, the second passivation layer includes a third interface opposite to the second interface, a nitrogen content and a silicon content at the second interface are higher than those at the first interface and the third interface, respectively, and an oxygen content at the second interface is lower than that at the first interface and the third interface, respectively.
