Abstract
A solar cell is provided, including: a substrate having a first surface including first regions and second regions, a first passivation contact structure formed on the first and second regions, second passivation contact structures formed on the first passivation contact structure, first passivation films formed on the first passivation contact structure, and first electrodes extending in a second direction perpendicular to the first direction. Each second passivation contact structure has an orthographic projection on the first surface in a respective first region, and each first passivation film has an orthographic projection on the first surface in a respective second region. Each first electrode covers a top surface of a respective second passivation contact structure and at least part of two opposing sidewalls of the respective second passivation contact structure in the first direction, and is in electrical contact with the respective second passivation contact structure.
