UNSW, DAS Solar build tunnel back-contact solar cell with 27% efficiency, lower silver content

Researchers from UNSW and DAS Solar developed a zero-busbar metal grid optimisation approach for tunnel oxide passivated back-contact (TBC) silicon solar cells, enabling more efficient current collection at the rear surface while reducing silver consumption by 3–4 mg/W. The first TBC cells produced in mass manufacturing using this technique have demonstrated efficiencies exceeding 27%.A research team comprising scientists from the University of …
