 by Flemming FunchScienceaGoGo reports on a discovery in materials for solar cells. It is sort of technical, but in brief the discovery is that an alloy of indium gallium nitride can convert pretty much the full spectrum of our sunlight, from the near infrared to the far ultraviolet, into electrical current. If they succeed in making practical solar cells of the material, they promise to be rugged, inexpensive, and more efficient than anything seen before. |
