The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells

open access: yesSmall, Volume 22, Issue 49, 1 September 2026.
ABSTRACT Tin perovskites are emerging as a sustainable alternative to lead‐based photovoltaics, yet their efficiency remains limited by energy‐level mismatch and intrinsic instability from tin oxidation. Progress is further hindered by inconsistent electrical behavior, obscuring the true bottlenecks of device performance.
