Perovskites Beyond Efficiency: Stability Challenges from Space to Earth

Abstract

To advance in metal halide perovskite (MHP) optoelectronics beyond efficiency, international collaboration is essential, with an emphasis on stability, cost, and scalability. MHPs demonstrate remarkable stability in extreme space-level radiation; nevertheless, their stability under everyday conditions, particularly when exposed to humidity and thermal cycling, remains a significant challenge. Strategies such as low-dimensional interface passivation, quantum-dot integration, and in situ synchrotron studies are among the methods emphasized in this Perspective to mitigate these problems. We propose pathways of collaborative research aimed at accelerating the development of durable, high-performance perovskite devices by synthesizing insights from the broader literature in conjunction with findings from a BRICS joint initiative project. This perspective is dedicated to the achievements of Professor Nam-Gyu Park, whose extensive and remarkable work on MHP has inspired this BRICS group to collaborate in addressing the challenges of this fascinating material.
