New Solar Cell Technology: 100 % Solar Efficiency

Posted on Wednesday, October 22, 2008 posted by posted by visa @ 5:42 AM

Researchers at Ohio State University have accidentally discovered a new solar cell material capable of absorbing all of the sun's visible light energy. The material is comprised of a hybrid of plastics, molybdenum and titanium. The team discovered it not only fluoresces (as most solar cells do), but also phosphoresces. Electrons in a phosphorescent state remain at a place where they can be "siphoned off" as electricity over 7 million times longer than those generated in a fluorescent state. This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency. Commercial products are still years away, but this foundational work may well pave the way for a truly renewable form of clean, global energy.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
