Summary: Chemical passivation of defective perovskite surface is a fundamental strategy to stabilize solar cell operation by impeding the defect-dominant surface ion migration. Here. we show that the configuration of organic cations plays a key role in determining their surface adsorption energetics at various perovskite facets. which will strongly impact the spatial uniformity of the... https://thegreensjunglebeautyshops.shop/product-category/neck/
