Diffusion‐Driven Targeted Passivation of Selenium Vacancies via an I‐Doped CdS Buffer Layer for Efficient Sb2Se3 Solar Cells

open access: yesAdvanced Science, EarlyView.
Iodine incorporation into the CdS buffer layer induces spontaneous anion diffusion and selectively passivates selenium vacancies in Sb2Se3 absorbers. The formation of low‐energy, charge‐neutral ISe defects effectively suppresses non‐radiative recombination, resulting in a substantially enhanced open‐circuit voltage and boosting the device efficiency to
