Researchers develop 'self-healing' dynamic passivation method for better perovskite solar cells
Researchers from Monash University, Xi’an Jiaotong University, Tunghai University, the University of Oxford, National Central University, and the City University of Hong Kong have developed a strategy to enhance the stability and performance of perovskite solar cells (PSCs) through a mechanism described as 'self-healing'.
The team reported a living passivation strategy using a hindered urea/thiocarbamate bond Lewis acid-base material (HUBLA), where dynamic covalent bonds with water and heat-activated characteristics can dynamically heal the perovskite to ensure device performance and stability.
