摘要

在文章编号2500319中，Nopporn Rujisamphan及其同事系统地研究了卤化胍盐（GuaX; X = I, Br, Cl）减轻钙钛矿晶界电荷积累的作用。他们证明了这些盐可以调节功函数，钝化缺陷，稳定晶界，从而改善晶粒均匀性，降低陷阱密度，增强载流子迁移率，抑制离子迁移 -最明显的是GuaCl。

Mitigating Surface and Grain Boundary Defects in Perovskite Solar Cells Through Guanidinium Halide Passivation

Perovskite Solar Cells

In article number 2500319, Nopporn Rujisamphan and co-workers systematically investigate guanidinium halide salts (GuaX; X = I, Br, Cl) for mitigating charge accumulation at perovskite grain boundaries. They demonstrate that these salts modulate work function, passivate defects, and stabilize grain boundaries, resulting in improved grain uniformity, reduced trap density, enhanced carrier mobility, and suppressed ion migrationâ€“most pronounced with GuaCl.

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.
