Nano-electronics research center imec announced at Intersolar Europe 2015, a new efficiency record for its large area n-type PERT (passivated emitter, rear totally diffused) crystalline silicon (Cz-Si) solar cell, now reaching 22.5 percent (calibrated at ISE CalLab).
It is the highest efficiency achieved for a two-side-contacted solar cell processed on six inch commercially available n-type Cz-Si wafers without the use of passivated contacts.
