Solar cell specs usually quote an open-circuit voltage and a short-circuit current. Between these extremes, the voltage that a solar cell can produce depends on how much current it’s producing.

Das Solar has achieved a world-record open-circuit voltage of 742 mV for an M10 n-type tunnel oxide passivated contact (TOPCon) solar cell, with a power conversion efficiency of 26.33%, according ...

DAS Solar has announced that it has broken the world record for a TOPCon 4.0 Plus high-efficiency cell by achieving an efficiency of 26.36% and an open-circuit voltage of 742mV.
