Ultrasonic Tinning Technology
Ultrasonic Tinning Technology In the photovoltaic industry, silver consumption is a key concern in achieving 100% renewable energy production. Current bifacial PERC+ solar cells rely on silver for the front-side contact. While aluminum metallization is used on the back side to contact the silicon, the aluminum's natural oxide layer hinders standard soldering, requiring back-side silver pads for interconnection between the cell and copper wires. This results in high silver consumption [...]
