Solar cells thinner than wavelengths of light hold huge power potential

Ultra-thin solar cells can absorb sunlight more efficiently than the thicker, more expensive-to-make silicon cells used today, because light behaves differently at scales around a nanometer (a billionth of a meter), say engineers. They calculate that an organic polymer thin film could absorb as much as 10 times more energy from sunlight than was thought possible.
