They used it to build a perovskite solar cell ... have been reported to impair device stability because of the hygroscopic nature and dopant-induced ion migration, which promotes perovskites ...

Although local defects in chloride-iodide-based perovskite are hard to avoid due to ion migration ... “When we compare the stability between two of our cells (control and champion), the samples ...

The elevated density of defect states generated during device preparation significantly influences the processes of charge recombination and ion migration. A team of IIT ... (Wiley), the team managed ...
