Researchers in Singapore set a 24.35% efficiency record for a perovskite PV cell



Singaporean researchers have achieved a world record 24.35% efficiency with 1 cm² inverted perovskite solar cells. The latest version of “Solar Cell Efficiency Tables” contains the result.

Researchers from various research units in Singapore have achieved a world record 24.35% power conversion efficiency in a 1 cm2 inverted perovskite solar cell. The achievement is included in version 62 of the “Solar Cell Efficiency Tables”.

The team said it improved the cell’s efficiency from 23.7 percent by using a “new interface material.”

“The introduction of this new interface material brings out a series of advantageous properties, including excellent optical, electrical and chemical properties,” the researchers said. “These properties work synergistically to improve the efficiency and longevity of perovskite solar cells, paving the way for significant improvements in their performance and durability.”

“Solar Cell Efficiency Tables” show that the cell achieved a breakdown voltage of 1.159 V, a short-circuit voltage of 25.60 mA/cm2 and a duty factor of 82.1%. The researchers said that the surface area of ​​a cell is 1.007 cm².

“This work represents the first case of a reverse-structure perovskite solar cell that outperforms normal-structure perovskite solar cells in an active region of 1 cm2and this is mainly due to the innovative charge-carrying material incorporated into our perovskite solar cells,” the researchers said. “Since inverted-structure perovskite solar cells always offer excellent stability and scalability, achieving higher efficiency than normal-structure perovskite cells is a significant milestone in the commercialization of this cutting-edge technology.”

The research team includes researchers from the National University of Singapore (NUS) and the Solar Energy Research Institute of Singapore (SERIS).
