New solar power material can capture every color of the rainbow

Scientists have created a new material that could dramatically increase the efficiency of solar cells, by literally capturing every color of the rainbow.

Whereas other materials only catch a small range of light frequencies, and therefore only a small fraction of the potential energy, the new invention is capable of absorbing all the energy contained in sunlight. According to team leader, Prof. Malcolm Chisolm, “There are other such hybrids out there, but the advantage of our material is that we can cover the entire range of the solar spectrum.

The discovery, made by an elite team at Ohio State University, opens the door to the development of a new generation of hyper-efficient solar cells. Although at this point the material is said to be some years from commercial development, the university has enough confidence in its potential to commit a large slice of its $100 million ‘high impact’ research budget to the research team over the next five years.

Such long-term investment lends a great deal of credibility to the project, and is likely to increase the chances of the invention moving from the laboratory towards commercial development.
