Abstract
Reducing the silver consumption of photovoltaics (PV) is a major aspect in recent solar cell research. For PERC+ solar cells silver is used for the front contact and as solder pads on the rear side. An ultrasonic (US) soldering process is used to wet Al structures on the rear side of PERC+ with lead-free solder and manufacture silver-free solder pads for the standard tabbing process. Peel tests are carried out showing an adhesion of above 2 N/mm of the cell interconnects. Contact resistance measurements are performed showing a comparable contribution to the series resistance as silver solder pads. Minimodules are fabricated reaching the same efficiency as a reference module with standard silver pad rear side connection and a degradation of less than 3.6% after 200 humidity-freeze cycles.
