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 made the announcement on the college’s LinkedIn account.
“Pleased to announce that we have now obtained a licensed energy conversion effectivity of 33.2% for our monolithic perovskite/silicon tandem solars cells developed on the KAUST Photo voltaic Heart,” he stated. “With this, the perovskite/silicon tandem is now essentially the most environment friendly two-junction photo voltaic cell know-how below normal illumination situations, even higher than III-Vs.”
The European Photo voltaic Take a look at Set up (ESTI) confirms the outcome.
“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 primarily based 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, primarily based 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 primarily based on magnesium fluoride (MgFx) positioned between the perovskite layer and the opening transport layer (HTL), to cut back the voltage loss.
