摘要

过氧化物太阳能电池硫代烟酰胺作为一种多功能路易斯碱添加剂，可通过吡啶、氨基和 S 基与不饱和铅原子配位，钝化缺陷态并减少卤化铅过氧化物薄膜中的非辐射重组。这就减少了晶界缺陷，提高了结晶度和功率转换效率，从而增强了器件的稳定性。更多信息请参见文章编号 2400589，Rajiv K. Singh 及其合作者。

Revealing Defect Passivation and Charge Extraction by Ultrafast Spectroscopy in Perovskite Solar Cells through a Multifunctional Lewis Base Additive Approach

Perovskite Solar Cells

Thionicotinamide as a multifunctional Lewis base additive passivates defect states and reduces non-radiative recombination in lead halide perovskite films by coordinating with unsaturated Pb atoms via pyridine, amino, and S group. This reduces grain boundary defects, improves crystallinity and power conversion efficiency, leading to enhanced device stability. More in article number 2400589, Rajiv K. Singh and co-workers.

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.
