KAUST claims 33.7% efficiency for perovskite/silicon tandem solar cell – pv magazine International

Scientists led by KAUST in Saudi Arabia achieved an influence conversion effectivity of 33.7% for a perovskite-silicon photo voltaic cell. KAUST Professor Erkan Aydin made the announcement on his LinkedIn account.

“Inside two months, we have set a brand new world file for perovskite/silicon tandem photo voltaic cells—once more! In our newest replace, the perovskite/silicon tandem photo voltaic cells reached a powerful 33.7% licensed energy conversion effectivity, surpassing our earlier milestone of 33.2%. We hope that our new achievement will contribute to the acceleration of the inexperienced power transition,” he stated.

The European Photo voltaic Take a look at Set up (ESTI) confirms the outcome.

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

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 high 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 scale back the voltage loss.
