    Products
    Pattern Transfer Printing (PTP)
    Product Introduction
    This system fills conductive paste into specially designed micro-grooves on a polymer film. A high-power laser beam is then used to align and scan, transferring the paste precisely onto the cell surface to form metallic gridlines. The process enables non-contact, pressure-free printing with narrower line widths and higher aspect ratios, improving cell conversion efficiency, reducing paste consumption, and lowering manufacturing costs.
    Product Features

    Enables ultra-narrow line widths with 20%–50% paste savings

    Adjustable aspect ratio from 10% to 80%, minimizing shading loss and boosting light-to-electricity conversion efficiency

    High print consistency enhances electrical conductivity; compatible with low-temperature pastes

    Non-contact, pressure-free printing significantly reduces breakage rate

    Compatible with customized line patterns to maximize light reflection in lamination and increase module output

    Supports a wide variety of advanced solar cell architectures

    Designed for high-volume manufacturing with scalable output
