As perovskite photovoltaics edge toward gigawatt production, buried SnO 2 /perovskite defects and iodine-volatilization losses still cap industrial yield. Now, researchers from Beijing National Laboratory for Molecular Sciences, CAS, led by Prof. Jizheng Wang, report a single-molecule “all-in-one” additive—ammonia borane (BNH 6 )—that is spin-coated on both the electron-transport and hole-transport sides of the perovskite layer during normal processing. Published in Nano-Micro Letters , the treatment lifts certified efficiency to 25.98 % and retains 90 % of that value after 500 h continuous illumination without encapsulation.
