Abstract
The solar cell includes a substrate having electrode regions and non-electrode regions alternatingly. The electrode regions have a first surface, the non-electrode regions have a second surface, and the first surface has a smaller roughness than the second surface. The solar cell further includes a first tunneling dielectric layer formed over the first surface, a first doped conductive layer arranged on a side of the first tunneling dielectric layer, a passivation layer formed over the second surface and the first doped conductive layer, and at least one first electrode. The at least one first electrode are arranged in the electrode regions, each of the at least one first electrode includes a connecting electrode formed over the electrode regions and multiple spot electrodes. The multiple spot electrodes are arranged below the connecting electrode and connected to the connecting electrode.
