Laser Secondary-Induced Sintering Equipment
Application Scenarios
By directing a high-energy laser beam onto the battery surface, charge carriers are excited to generate a localized, high-density current.
Simultaneously, a reverse bias voltage is applied; the combined effect of the laser irradiation and the reverse bias
induces a high-density current flow across the contact interface at specific localized points.
This process triggers mutual diffusion between the metal grid lines and the silicon substrate,
establishing a robust silver-silicon contact that effectively reduces contact resistance.
Crucially, this is achieved without causing widespread damage to the passivation layer,
thereby enabling an increase in both open-circuit voltage and short-circuit current.
Consequently, the overall conversion efficiency of the solar cell is significantly enhanced.
