Overview
High-energy laser irradiation excites carriers on the surface of the battery to form a local high-density current, and at the same time applies a reverse bias voltage. The laser irradiation and reverse bias voltage result in a high current density at a local location through the contact interface, triggering mutual diffusion between the metal grid lines and the silicon matrix, forming a good silver-silicon contact, effectively reducing the contact resistance, without causing large-area damage to the passivation layer, thus increasing the open voltage and short-circuit current, thereby significantly improving the conversion efficiency of the cell.
