Passivation of the Buried Interface via Preferential Crystallization of 2D Perovskite on Metal Oxide Transport Layers
Published in Advanced Materials 2021, 33 (41), e2103394, 2021
Organic spacer cations bearing −NH2 groups preferentially bind to under-coordinated oxygens on metal oxide substrates, inducing spontaneous 2D perovskite crystallization at the buried interface that reduces surface recombination velocity by 72% and enables up to 22.9% PCE in inverted solar cells.
