The Gallium Arsenide Flexible Solar Cell Plating Machine is a specialized equipment designed for depositing metal electrodes on flexible, ultra-thin gallium arsenide solar cell substrates. Its core challenge lies in achieving high conductivity, excellent ohmic contact, and strong adhesion of electrodes on flexible substrates that are sensitive to high temperatures and prone to warping.

Through a precision roll-to-roll or single-piece transfer system, the equipment integrates pre-treatment, plating, and post-treatment units, employing low-temperature, low-stress specialized plating processes. It enables precise deposition of metal layers such as nickel, gold, or silver in specific areas of the cell, forming grid electrodes that collect and conduct photogenerated current, while ensuring the electrodes maintain stable electrical and mechanical performance even under repeated bending of the cell.
