Black Silicon Solar Cell Hits 18.2% Efficiency, Should Help to Reduce Costs

“The researchers made nano-islands of silver on a silicon wafer and immersed it briefly in liquids to make billions of nano-sized holes in each square-inch of the silicon wafer surface,”an NREL news release states. “The holes and silicon walls are smaller than the light wavelengths hitting them, so the light doesn’t recognize any sudden change in density at the surface and, thus, don’t reflect back into the atmosphere as wasted energy. The researchers controlled the nanoshapes and the chemical composition of the surface to reach record solar cell efficiencies for this ‘black silicon’ material.”

Huh, I thought Germany was doing something, not similar, but just as efficient. diff technique. maybe they should talk. [link]
