Nonradiative recombination originating from the defect-rich SnO2/perovskite buried contact and the absorber interior imposes a major constraint on photovoltaic output and device durability. Here, ethylenediaminetetraacetic acid dipotassium salt (EDTA-2K) is inserted as a molecular bridge that modifies the chemical envi...

Currently, high-efficiency perovskite solar cells (PSCs) are typically fabricated in an inert atmosphere, as oxygen or humid environments tend to induce the formation of the non-photovoltaically active δ-phase in the FAPbI3 system, leading to severe non-radiative recombination and energy loss, which limits device effic...
