Washington, Dec 24: Scientists have come up with a new approach to help solar cells harvest light more efficiently, by lacing them with nanoscopic metal particles.
Like plants, solar cells turn light into energy. Plants do this inside vegetable matter, while solar cells do it in a semiconductor crystal doped with extra atoms.
Current solar cells cannot convert all the incoming light into usable energy because some of the light can escape back out of the cell into the air.
Additionally, sunlight comes in a variety of colors and the cell might be more efficient at converting bluish light while being less efficient at converting reddish light.
The nanoparticle approach seeks to remedy these problems.
