Abstract:The development of perovskite solar cells (PSCs) has gone from strength to strength over the last decade, enabling low-cost, flexible and high-efficiency photovoltaic devices. However, the significance of molecular iodine...
Highly deformable crosslinked polymer particles enhance perovskite solar cell passivation and stability by binding and distributing throughout the film.
This study showed PEHCl-CN can enhance the strength of Sn–I, resulting in good light stability. The subsequent doping of MBI resulted in good air stability. This enables the integrated 2T all-perovskite device to achieve an efficiency of 27.9%.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
