Partners at King Abdullah University of Science and Technology (KAUST), in collaboration with international partners, have achieved a new record: a 28.7% efficiency perovskite–perovskite–silicon triple-junction tandem solar cell.
This device uses stabilized perovskite layers to improve both performance and long-term stability, addressing challenges that have limited tandem structures in the past.
"These multijunction solar cells require more layers as the number of junctions increases, and the consistency of the deposited layers is quite critical. We have been using the Angstrom systems for years, and they have been serving us very well." Dr. Aydin said, who is a co-author of the study.
