Steps forward in the research for iron-based solar cells

A group of researchers at Lund University in Sweden have made the first iron-based molecule capable of emitting light. This could contribute to the development of affordable and environmentally friendly materials for e.g. solar cells, light sources and displays.
Modern alchemy creates luminescent iron molecules

For over 50 years, chemists have developed metal-based dye molecules for a wide range of different applications, such as displays and solar cells. This would ideally involve common and environmentally friendly metals like iron, but despite a number of attempts no one has been able to develop an iron-based dye molecule that can emit light until now. Researchers around the world have therefore instead largerly had to resort to various rare and precious metals, such as ruthenium, which have more easily provided the desired properties.

Through advanced molecular design, the Lund researchers have now successfully manipulated the electronic properties of iron-based molecules so that they much better resemble the ruthenium-based substances.
