Abstract

Thin-Film Solar Cells

In article number 2500212, Yun Seog Lee and co-workers systematically explore chelation-driven passivation strategies for Pb-related surface defects in perovskite films utilizing organic acids with varying numbers and types of functional groups. Among the tested molecules, citric acid—featuring multiple carboxyl and hydroxyl groups—exhibits the strongest interaction with uncoordinated Pb²⁺ ions. This effective passivation leads to significant improvements in both the power conversion efficiency and long-term operational stability of the devices.

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.
