Solar cell improvements

Except:

Solar cells thinner than wavelengths of light hold huge power potential, Stanford researchers say

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 Stanford engineers. They calculate that by properly configuring the thicknesses of several thin layers of films, an organic polymer thin film could absorb as much as 10 times more energy from sunlight than was thought possible.

Now organic solar cells have become more popular. They are one of the best solar cell options on the market because of their availability and low price. More information here.
