Solar cells of the future could be based on iron molecules

Researchers at Lund University - NanoLund - have successfully explained how iron-based dyes work on a molecular level in solar cells. The new findings will accelerate the development of inexpensive and environmentally friendly solar cells.

 

 

The goal is to be able to use iron-based dyes in solar cells in the future. By using iron instead of other more expensive and rare metals, the production of solar cells and light catchers will become cheaper and more environmentally friendly. The demand for solar cells is therefore expected to significantly increase.

“In this new study, we explain how iron-based dyes work on a molecular level. That way we are able to further improve these iron complexes so that they become even better at absorbing and storing solar energy”, says senior lecturer Petter Persson.
