The European Solar Test Installation (ESTI) has confirmed the results of King Abdullah University of Science and Technology’s (KAUST) new perovskite/silicon tandem solar cell. KAUST researchers claim that the technology is a step forward compared to other perovskite silicon cells they have developed.

“We are pleased to announce that we obtained a certified power conversion efficiency of 33.2% for the monolithic perovskite/silicon tandem solar cells developed at the KAUST Solar Center,” he said. “As a result, perovskite/silicon tandems are now the most efficient dual-junction solar cell technology under normal lighting conditions, even better than III-V.”

European Solar Test Facility (PREVENTED) has confirmed the result.

“The 33.2 percent efficiency was just added to the NREL chart,” he said pv magazine. “The cells are really an improvement over our previous devices.”

KAUST announced in January 28.1% power conversion efficiency for a perovskite-silicon tandem solar cell based on textured silicon wafers. In August 2022, it claimed 26.2% efficiency for a monolithic perovskite-silicon tandem PV device.

In December 2021, KAUST researchers reached power conversion efficiency of 28.2% for a tandem solar cell with an area of ‚Äč‚Äčabout 1 cm2 based on a nip perovskite stacked on top of a silicon heterojunction.

The same research group recently announced an inverted perovskite-silicon tandem solar cell with a 1 nm magnesium fluoride (MgFx)-based interlayer sandwiched between the perovskite layer and the hole transport layer (HTL) to reduce voltage drop.
