Stanford's new solar cell uses "light trapping" to stop light from bouncing around as it does on normal solar cells, making these ultra thin cells absorb up to 10 times more sunlight. These new ultra thin cells are also "thinner than the wavelengths of light," about 400 to 700 nanometers thin. These cells are also made out of organic polymers, making them cheaper than current solar cells.
