Singapore team breaks perovskite solar cell efficiency record
Perovskite solar cells developed in Singapore have achieved a world record efficiency of 24.35 per cent with an active area of 1 cm2.
This achievement by scientists from the National University of Singapore (NUS) has the potential to lead to cheaper, more efficient and durable solar cells.
Prior to the record-breaking feat by the NUS team, the best 1cm2 perovskite solar cell recorded a power conversion efficiency of 23.7 per cent.
Perovskites exhibit high light absorption efficiency and ease of fabrication, making them promising for solar cell applications. In the past decade, perovskite solar cell technology has achieved several breakthroughs, and the technology continues to evolve.
“We undertook a dedicated effort to develop innovative and scalable technologies aimed at improving the efficiency of 1cm2 perovskite solar cells. Our objective was to bridge the efficiency gap and unlock the full potential of larger-sized devices,” said Assistant Professor Hou Yi, leader of the NUS research team comprising scientists from the Department of Chemical and Biomolecular Engineering under the NUS College of Design and Engineering, plus the Solar Energy Research Institute of Singapore (SERIS).
