3-D Surface to Boost Solar Cell Efficiency

Posted on Wednesday, March 25, 2009 posted by posted by Mak @ 10:40 PM

Researchers at the Georgia Institute of Technology have developed a new treatment for silicon photovoltaic solar cells that creates bumps and peaks on the surface that increase cell efficiency in two ways.The surface structures prevent water and dust from coming into contact with the cells. When water hits the surface, it beads together and runs off, collecting any dirt or dust along with it. This self-cleaning mechanism will help keep the solar cells working at maximum light absorption at all times.Additionally, the three-dimensional structures manage to capture more light and reflect less.

  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
