    Laser-Induced Firing System
    Product Introduction
    This system combines directional laser irradiation with electric-field-assisted secondary sintering to achieve ultra-fast localized heating. The process significantly reduces contact resistance, supports low-corrosivity pastes, minimizes damage to passivation layers, lowers metal recombination, and improves open-circuit voltage. It enhances solar cell conversion efficiency by more than 0.4% while reducing silver paste consumption by over 20%.
    Product Features

    Compact system footprint with single-sided operation and minimal space requirement

    Dual-lane configuration (Line A & B) supports independent operation and fast switching between online/offline modes

    Unique optical homogenization design enables full-surface scanning with large laser spots

    Probe compression mode with zero shading; easy setup and high equipment utilization

    Broad compatibility with various electrode patterns, including 0BB architecture

    Simultaneous sintering of both front and rear electrodes

    Built-in buffer zone prevents downtime during paste clogging; seamless loading/unloading transitions
