CANBERRA, Australia, Feb. 4, 2022 — Researchers at the Australian National University achieved a fill factor of more than 86%, breaking their previous record. According to the researchers, the conversion efficiency of state-of-the-art cells is limited by the cell’s fill factor — typically less than 83%, which is below the Shockley Queisser limit of approximately 90%. The team introduced a reverse-doping process to fabricate nitrogen-doped titanium oxide electron transport layers with outstanding charge transport performance, creating cells with fill factors greater than 86%, and an average fill factor of 85.3%. The research was published in Nature (

WETZLAR, Germany — Leica Microsystems, a manufacturer of microscopes and scientific instruments, opened its state-of-the-art Imaging Centre at the European Molecular Biology Laboratory (EMBL) in Heidelberg. The imaging center will serve as a hub to drive collaborative research.
