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.

Further details of the setup and the results are provided in the study “ Outdoor implied open-circuit voltage imaging of perovskite solar cells using sunlight excitation,” published in Joule.

Solar panel rating: 20W (12V) or 10W (6V) Output voltage range: 5 to 14V (adjustable) (may be reduced further by shorting R2) Max power dissipation: 10W (includes power dissipation of D1) Typical ...

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.
