Nanoscopic impurities trigger perovskite degradation

Article Multidisciplinary Sciences

Local nanoscale phase impurities are degradation sites in halide perovskites

Stuart Macpherson et al.

Summary: Understanding the nanoscopic chemical and structural changes is crucial for mitigating device degradation in emerging energy materials. Researchers have developed a multimodal microscopy toolkit to investigate the impact of phase impurities on the performance and longevity of formamidinium-rich perovskite absorbers. The study also demonstrates that manipulating these impurities can alleviate performance losses and intrinsic degradation processes.
