Abstract:As numerous studies on highly efficient perovskite solar cells have been conducted on lead‐based light absorbers, such as MAPbI3 and FAPbI3, increasing concerns are rising regarding toxicity and stability issues. One of the most prominent and promising lead‐free alternatives is the double‐perovskite Cs2AgBiBr6, which is well‐suited for multi‐junction solar cells considering its relatively large indirect bandgap of around 1.95–2.05 eV. Despite distinctive reports on its performance under ambient conditions, the… Show more
