Abstract
The defect is of great importance for perovskite solar cells (PSCs). During device aging, the already well-passivated perovskite can still generate new defects. Traditional passivating approaches are unable to well passivate these newly generated defects, thus affecting device performance. Herein, a thermal-triggered sustainable defect passivation strategy is proposed by employing a heat-induced molten passivator of perfluorobutylsulphonamide (PBSA). PBSA will change to liquid after heat treatment, flowing to the generation sites of new defects and passivate them, thus inducing degraded efficiency recover and enhancing device stability. Resulting PSCs with PBSA exhibit high efficiency of 24.34% with good stability, retaining >90% of initial efficiency after ultraviolet aging for 500 h.

期刊介绍：
Solar RRL, formerly known as Rapid Research Letters, has evolved to embrace a broader and more encompassing format. We publish Research Articles and Reviews covering all facets of solar energy conversion. This includes, but is not limited to, photovoltaics and solar cells (both established and emerging systems), as well as the development, characterization, and optimization of materials and devices. Additionally, we cover topics such as photovoltaic modules and systems, their installation and deployment, photocatalysis, solar fuels, photothermal and photoelectrochemical solar energy conversion, energy distribution, grid issues, and other relevant aspects. Join us in exploring the latest advancements in solar energy conversion research.
