Improving Moisture/Thermal Stability and Efficiency of CH3NH3PbI3‐Based Perovskite Solar Cells via Gentle Butyl Acrylate Additive Strategy.

Consequently, the device with butyl acrylate additive delivers a high power conversion efficiency of 20.0% and superior moisture/thermal stability under ambient conditions. Improving Moisture/Thermal Stability and Efficiency of CH₃NH₃PbI₃-Based Perovskite Solar Cells via Gentle Butyl Acrylate Additive Strategy B Perovskite Solar Cells b In article number 2000621, Wei Wang, Zongping Shao, and co-workers introduced a gentle butyl acrylate additive into MAPbI SB 3 sb -based perovskite solar cells to enhance the efficiency and stability by improving perovskite film quality, constructing suitable energy level alignment and increasing charge carrier lifetime.
