Unlocking Perovskite Solar Cell Stability Secrets

• Uncover the key to perovskite solar cell stability: ion-induced field screening. Discover how researchers are revolutionizing next-gen solar technology in Nature Energy.

Researchers from the University of Potsdam and other universities have found that ion-induced field screening is a key factor in the operational stability of perovskite solar cells. Published in Nature Energy, their study provides insights for enhancing the lifetime of these next-generation solar cells, which have surpassed traditional silicon-based technologies in performance. Despite this, perovskite stability still lags behind silicon cells by about ten times.

The study challenges the common belief that electronic defects are the main cause of perovskite degradation. Instead, the researchers discovered that the creation of mobile ions under external stressors in the perovskite semiconductors leads to charge extraction losses, affecting operational stability. By understanding this mechanism, new strategies can be developed to improve the lifetime of perovskite cells and accelerate the development of more stable versions.
