KAUST postdoctoral fellow Esma Ugur displays the perovskite/silicon tandem solar cell that she and colleagues in the KAUST Photovoltaics Laboratory developed. It is currently the world’s most efficient silicon/perovskite tandem solar cell, with a power conversion efficiency of 33.2%. (Courtesy: KAUST)
It’s been a good couple of months for perovskite solar cells, with a trio of new results that coul
