SOLAR CELL BREAKTHROUGHS
SOLAR CELL BREAKTHOUGHS
Currently under development is a new solar cell technology that is said to be about 90% efficient. The silicon wires absorb up to 96 percent of “incident sunlight” and 85 percent of “collectible sunlight,” breaking previous records. These solar cells are also not primarily made of silicon but 98% plastic, which will significantly reduce the cost as an added and tremendous bonanza.
SOLAR REVOLUTION IN THE MAKING
This offers the prospect of revolutionizing energy production here and around the world. It can get everyone of the grid. These cells are currently under development at the California Institute of Technology.
WHAT THE NEW SOLAR CELLS CONSIST OF
The new solar cells have tiny silicon wires that measure just 1 micron, thus using minimal silicon in their construction. These wires are strung into plastic plates where they more efficiently convert sunlight into solar power. Only two percent of the cell is composed of semi-conductors. They are about the same thickness as conventional solar cells.
Nanosolar has developed a highly thin roll-out printed on metal foil solar technology that currently is only used for commercial purposes. It is competitive with coal’s generation of electrical energy and gets 15-16% efficiency but at a very low cost. It was named the best invention of the year for 2008 by Time Magazine
The development of new solar cells that are both more efficient and less costly portends that solar power will soon go mainstream.
PROTECTING OUR PLANET
With new renewable energies we can stop the current drift toward increasing global warming and other non-sustainable trends.
