[font face=Serif][font size=5]Breakthrough for iron based dyes can lead to cheaper and environmentally friendly solar energy applications[/font]

Published: 13/10/2015

[font size=4]Researchers at Lund University in Sweden have found a new way to capture energy from sunlight – by using molecules that contain iron. The results are presented in the latest issue of Nature Chemistry. The hope is to develop efficient and environmentally friendly solar energy applications.[/font]

“The advantage of using iron is that it is a common element in nature. It can provide inexpensive and environmentally friendly applications of solar energy in the future”, says Kenneth Wärnmark, Professor of Organic Chemistry at Lund University.

By combining the experiments with advanced computer simulations, the researchers are able to understand in detail required design concepts for the iron molecules to work. This knowledge is now being used for further developing the iron-based dyes. More research is needed before the new solar cell dye can be used in practice, but there are high hopes.

“The results of the study suggest that solar cells based on these materials can be at least as effective as those of today that are based on ruthenium or other rare metals”, says Villy Sundström.
