Abstract
A solar cell includes a substrate having a front surface and a back surface opposite to the front surface; a first passivation layer, a second passivation layer and a third passivation layer sequentially formed on the front surface of the substrate and in a direction away from the substrate; where the first passivation layer includes a dielectric material; the second passivation layer includes a first SiNmaterial, and a value of v/u is 1.3≤v/u≤1.7; and the third passivation layer includes a SiOmaterial, and a value of s/r is 1.9≤s/r≤3.2; and a tunneling oxide layer and a doped conductive layer sequentially formed on the back surface of the substrate and in a direction away from the back surface; the doped conductive layer and the substrate are doped to have a same conductivity type.
