KAUST team announces 33.7% efficiency for perovskite/silicon tandem solar cell

Less than two months after achieving a new world record for tandem solar cell efficiency of 33.2%, KAUST researchers have announced an improvement to this number by reaching a power conversion efficiency of 33.7% for a perovskite-silicon solar cell. 

The result was reportedly certified by the European Solar Test Installation (ESTI).


The 1 cm2 cell also achieved an open-circuit voltage of 1.974 V, a short-circuit current density of 20.99 mA/cm2, and a fill factor of 81.3%.

KAUST Professor Erkan Aydin made the announcement on its LinkedIn account, also mentioning that "This achievement is a great teamwork together with Esma Ugur, Thomas Allen, and the entire KPV-Lab team of KAUST Solar Center (KSC). KPV-Lab is headed by Stefaan De Wolf".
