Selenium Can Significantly Improve Solar Cells Efficiency
4 August 2010 | Solar Power | 2 Comments
The American Institute of Physics, published a journal which describes how solar power could be harvested more efficiently using oxide materials containing selenium. In this journal, was described how a team of researchers in Berkeley, California, have successfully tested the efficiency of the element selenium in solar cells. Besides the fact it is a relatively cheap material, only a small amount of selenium increased significantly the ability of solar cells to absorb light.
Selenium could improve solar cells efficiency
Obtaining such highly efficient solar cells, researchers could deepen their studies on photoelectrochemical water splitting for example. Splitting water into oxygen and hydrogen using solar cells could be the key to generating hydrogen for future zero-emissions vehicles.
“Researchers are exploring ways to make solar cells both less expensive and more efficient; this result potentially addresses both of those needs,” says author Marie Mayer, a fourth-year University of California, Berkeley doctoral student. Being realistic, she believes that we won’t see too soon many hydrogen powered cars on the roads, but she says “if you can dream it, someone is trying to research it.”

The Solar panel that collects the energy that comes from the rays of the sun and use it up as power during the night time. No worry about the electric bills because in Solar lamps you can save energy and time. so why don’t switch on solar lamps.
In Solar lamps you just have to find them a nice appropriate location in your garden where they can receive the maximum amount of sun rays, it’s very efficient and convenient to used.
