Perovskite tandem solar cell: Power generation efficiency of 33.2% achieved!
– Royal Abdullah University of Science and Technology Sets World Record –
From the latest report of fabcross for engineers
Saudi Arabia: Royal Abdullah University of Science and Technology (KAUST)
KAUST has developed a perovskite tandem solar cell and achieved the world’s highest power generation efficiency.
Capabilities of tandem solar cells:
Conventional crystalline silicon solar cells have module efficiencies of 20-22%.
In this solar cell, the upper perovskite layer absorbs blue light and the lower silicon layer absorbs red light.
Collect sunlight efficiently. It replaces conventional crystalline silicon solar cells.
KAUST Research Team:
This time, we have achieved a power generation efficiency of 33.2% for tandem solar cells.
Exceeds the highest efficiency of 32.5% of the Berlin Institute of the Helmholtz Association in Germany.
European Photovoltaic Testing Institute (ESTI) certification
It was placed at the top of the Best Research-cell Efficiency Chart.

KAUST team sets world record for tandem solar cell efficiency
Crystalline silicon solar cells dominate the global photovoltaic market with module efficiencies around 20-22%.
However, the field of solar energy is wanting for innovative materials and approaches that yield even higher efficiencies in support of global renewable energy goals.
Tandem solar cells combining silicon and perovskite sub-cells are widely regarded as a promising,
high performing and viable alternative to conventional crystalline solar cells,
King Abdullah University of Science and Technology (KAUST) is leading the charge.

Researchers in the KAUST Photovoltaics Laboratory (KPV-Lab) of the KAUST Solar Center have produced a perovskite/silicon tandem solar cell with a power conversion efficiency (PCE) of 33.2%
— the highest tandem device efficiency in the world to date,
surpassing that of Helmholtz Zentrum Berlin’s (HZB) record at 32.5% PCE.
The tandem device was certified by the European Solar Test Installation (ESTI)
and listed at the top of the National Renewable Energy Laboratory’s (NREL), Best Research-cell Efficiency Chart.
