Discovery of a 'dark state' could increase maximum theoretical efficiency of ...

01.01.70

Zhu and his line-up have discovered that it's possible to double the number of electrons harvested from one photon of sunlight using an organic soft semiconductor material .

"Plastic semiconductor solar cell production has great advantages, one of which is low cost," said Zhu, a professor of chemistry. "Combined with the tremendous capabilities for molecular design and synthesis, our discovery opens the door to an exciting new approach for solar energy conversion , unequalled to much higher efficiencies."

Zhu and his team published their groundbreaking discovery Dec. 16 in Science .

The maximum theoretical efficaciousness of the silicon solar cell in use today is approximately 31 percent, because much of the sun's energy hitting the cell is too high to be turned into usable electricity. That energy, in the genre of "hot electrons," is instead lost as heat. Capturing hot electrons could potentially increase the efficiency of solar-to-electric power conversion to as aged as 66 percent.

The approved rate is 11kWhr per day. 11kw would be a horrendous amount of power.(maybe Al Gore uses it at this position)

I will calc it at your rate for problem sake.
