Abstract
The method for preparing a solar cell includes providing a substrate having a first surface and a second surface opposite to the first surface; forming a doped layer and a first passivation layer stacked sequentially in a direction away from the substrate on the first surface; forming a second passivation layer on the second surface; forming multiple first grid line electrodes arranged at intervals on the surface of the first passivation layer away from the substrate, and forming multiple second grid line electrodes arranged at intervals on the surface of the second passivation layer away from the substrate; performing a laser processing on the multiple first grid line electrodes and an adjacent region of the multiple first grid line electrodes, and applying a reverse current between the multiple first grid line electrodes and the multiple second grid line electrodes.
