Abstract
The solar cell includes a substrate having electrode regions and non-electrode regions defined alternatively, where a surface of the electrode regions has a first surface structure, a surface of the non-electrode regions has a second surface structure, the first surface structure has a smaller roughness than the second surface structure, and the second surface structure includes multiple first protrusion structures. The solar cell further includes a tunneling dielectric layer, and a first doped conductive layer arranged on the tunneling dielectric layer. The solar cell further includes a passivation layer arranged on the non-electrode regions and the first doped conductive layer and a first electrode arranged in the electrode regions. The first electrode penetrates the passivation layer to be in electrical contact with the first doped conductive layer.
