Perovskite Solar Cell Breaks World Record Again

Recently, researchers at King Abdullah University of Science and Technology (KAUST) in Saudi Arabia recorded a 33.2% power conversion efficiency in a perovskite/silicon tandem solar cell, which they claim is a new world record for the technology. The

European Solar Testing Institute (ESTI) has certified the results. Stefaan De Wolf, temporary deputy director

of KAUST Solar Energy Center, said that this new record is the highest PCE of all double-junction solar cells under non-concentrated light, which proves the great prospect of perovskite/silicon tandem to provide ultra-high performance photovoltaic modules. This is essential for the rapid achievement of renewable energy targets to combat climate change.

KAUST said in its release that the perovskite tandem technology is expected to capture a $10 billion market share by 2032.

It is reported that although KAUST did not provide the size of the test unit, its researchers said that they were studying ways to extend the technology to more than 240c ㎡ units. In

January, KAUST announced that the power conversion efficiency of perovskite-silicon tandem solar cells based on textured silicon wafers was 28.1%. In August

2022, the company claimed an efficiency of 26.2% for a monolithic perovskite-silicon tandem photovoltaic device. In December

2021, KAUST researchers achieved a power conversion efficiency of 28.2% on a tandem solar cell with an area of about 1 square centimeter, based on n-i-p perovskite stacked on a silicon heterojunction.

The research group recently announced an inverted perovskite-silicon tandem solar cell with a 1-nanometer magnesium fluoride (MgFx) interlayer placed between the perovskite layer and the hole transport layer (HTL) to reduce voltage loss.
