A US-Canadian group of scientists has used Lewis base molecules to improve surface passivation in a perovskite solar cell. The team produced a device with a high open-circuit voltage and remarkable stability levels.A US-Canadian research team has fabricated an inverted perovskite solar cell by using Lewis base molecules for surface passivation. Lewis bases are generally used in perovskite solar research to passivate surface defects in the perovskite layer. This has positive effects on energy level alignment, interfacial recombination kinetics, hysteresis behavior, and operational stability. "Lewis ...Den vollständigen Artikel lesen ...
