JA Solar said the result was achieved for its Bycium+ solar cell, which reached a power conversion efficiency of 26.07%, an open-circuit voltage of 748.6 mV, a short-circuit current of 13.71 mA ...

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.
