The European Solar Test Installation (ESTI) has actually validated the outcomes of King Abdullah University of Science and Technology’s (KAUST) brand-new perovskite/silicon tandem solar battery. KAUST scientists declare the tech is an advance from other perovskite-silicon cells they have actually established.

Researchers led by Saudi Arabia’s KAUST have actually accomplished a power conversion performance of 33.2% for a perovskite-silicon solar battery. KAUST Professor Stefaan De Wolf made the statement on the university’s LinkedIn account.

“Glad to reveal we acquired a licensed power conversion effectiveness of 33.2% for our monolithic perovskite/silicon tandem solars cells established at the KAUST Solar Center,” he stated. “With this, perovskite/silicon tandems are now the most effective two-junction solar battery innovation under basic lighting conditions, even much better than III-Vs.”

The European Solar Test Installation (ESTIhas actually accredited the outcome.

“The 33.2% effectiveness was simply contributed to the NREL chart,” he informed pv publication“The cells are certainly a more enhancement on our previous gadgets.”

In January, KAUST revealed a power conversion effectiveness of 28.1% for a perovskite-silicon tandem solar battery based upon textured silicon wafers. In August 2022, it declared a 26.2% effectiveness for a monolithic perovskite-silicon tandem photovoltaic gadget.

In December 2021, KAUST scientists attained a power conversion performance of 28.2% for a tandem solar battery with a location of around 1 cm2, based upon an n-i-p perovskite stacked on top of a silicon heterojunction.

The exact same research study group just recently revealed an inverted perovskite-silicon tandem solar battery with a 1 nm interlayer based upon magnesium fluoride (MgFx) positioned in between the perovskite layer and the hole transportation layer (HTL), in order to lower voltage losses.
