Bismuth Oxyiodide (BiOI)—A Non-toxic Alternative To Solar Cells
Bismuth is considered as a "green-element" and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of the University of Cambridge and the United States developed theoretical and experimental methods to show that...
