The Role of Interfacial Energetics and Defects on The Efficiency of Tin Perovskite Solar Cells. [PDF]
SmallABSTRACT 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.

Co-Doping Approach for Enhanced Electron Extraction to TiO<sub>2</sub> for Stable Inorganic Perovskite Solar Cells. [PDF]
Small SciTiO2 is highly relevant in photoelectrochemistry, (photo)catalysis, and sensor applications, where high conductivity is crucial. Herein, a co‐doping strategy for TiO2 using Nb(V) and Sn(IV) is developed, enhancing electron extraction from perovskite and improving solar cell efficiency and stability.
