In their quest to produce more-sustainable luminescent materials and catalysts for the conversion of sunlight into other forms of energy, University of Basel researchers have developed a class of compounds based on manganese. The metal is more abundant — and cheaper — than iridium, as well as less toxic.
Iridium is commonly used in OLEDs. Ruthenium, used in solar cells, is another stable element that is very rare. The advancement could lead to using manganese in solar cells. Manganese is, in fact, 900,000 times more abundant in Earth’s crust than iridium, which is rarer than gold or platinum.
The team led by Oliver Wenger and Patrick Herr specifically produced luminescent manganese complexes in which exposure…READ MORE
