Abstract
Provided are a solar cell and a tandem solar cell. The solar cell includes a substrate, a tunnel dielectric layer, a doped conductive layer, a first passivation layer and a first electrode. A first surface of the substrate includes metal regions having a first texture structure including a first recess, and non-metal regions having a second texture structure including a second recess. A one-dimensional size of a bottom surface of the first recess is smaller than that of the second recess. The tunnel dielectric layer is arranged at the first texture structure. The doped conductive layer is arranged at a side of the tunnel dielectric layer. The first passivation layer is arranged at a side of the doped conductive layer and at the second texture structure. The first passivation layer includes a third region and a fourth region. The first electrode is electrically connected to the doped conductive layer.
