Scientists led by KAUST in Saudi Arabia achieved an influence conversion effectivity of 33.2% for a perovskite-silicon photo voltaic cell. KAUST Professor Stefan De Wolf introduced on the college’s LinkedIn account.
“Completely happy to announce that now we have obtained a licensed energy conversion effectivity of 33.2% for our monolithic perovskite/silicon tandem solars cells developed on the KAUST Photo voltaic Middle,” he stated. “With this, the perovskite/silicon tandem is now probably the most environment friendly two-junction photo voltaic cell expertise underneath commonplace illumination situations, even higher than III-Vs.”
The European Photo voltaic Check Set up (ESTI) confirms the consequence.
“The 33.2% effectivity is simply added to the NREL chart,” he stated pv journal. “The cells are literally an extra enchancment over our earlier gadgets.”
In January, KAUST introduced an influence conversion effectivity of 28.1% for a perovskite-silicon tandem photo voltaic cell based mostly on textured silicon wafers. In August 2022, it claimed 26.2% effectivity for monolithic perovskite-silicon tandem photovoltaic gadgets.
In December 2021, KAUST researchers achieved an influence conversion effectivity of 28.2% for a tandem photo voltaic cell with an space of 1 cm2, based mostly on a nip perovskite layered on prime of a silicon heterojunction.
The identical analysis group lately reported an inverted perovskite-silicon tandem photo voltaic cell with a 1 nm interlayer based mostly on magnesium fluoride (MgFx) positioned between the perovskite layer and the outlet transport layer (HTL), to cut back the voltage loss.
*The article was up to date on April 13 to notice that the European Photo voltaic Check Set up (ESTI) confirmed the consequence.
