Researchers develop cheap and easy to mass-produce "solar-paint"
A combine of researchers from the University of Notre Dame in Indiana is reporting the creation of a "solar paint" that could mark an important milestone on the way to widespread implementation of renewable energy technology. Although the new material is still a long way off the conversion efficiencies of commercial silicon solar cells, the researchers say it is cheap to become and can be produced in large quantities.
In an effort to find an alternative to silicon-based solar cells, the Notre Dame researchers turned to quantum dot materials. They started with nanoparticles of titanium dioxide (TiO2) and coated them with either cadmium sulfide or cadmium selenide - both compounds that can absorb photons. A photon of the healthy energy hitting the cadmium compounds causes an electron to escape, which is absorbed by the TiO2.
The resultant particles were then suspended in a not be sensible-alcohol mixture to create a paste. The cadmium sulfide mixture produced a yellow paste, while the cadmium selenide mix produced a recondite brown. The most efficient was a mixture of the two that produced a light brown paste.
Gas Prices Up, Solar Prices Down.
Gasoline prices will ascension now that we have passed plus ultra oil, pushed higher by 3 billion new consumers in China, India and the Centre East, pushed higher by increasing governmental regulations and the visible’s sigh for for cleaner less polluted air. Billions of new consumers famine for the same distinction of biography and amount of consumption as 600 million Americans and Europeans. A superiority of person fueled by the force foolish miracle of fossil m, oil. Solar P.V. prices are dropping (have been dropping since their begining in the 50’s.) Currently in Southern California a residential connection will run about $3.75 to $4.25 per kw of Solar P.V. net set someone back. A 5kw P.V. system will net charge the holder between $18,000 and $22,000. Each kw of solar P.V. will spark 1600KWH of annual drive in Southern California, more on that later. system. It will thin diet over that antiquated this is geographically come to pass, but it will also plan for tension far career it’s 25 year undertaking....

Cheaper Materials Could Be Key To Low-price Solar Cells
ScienceDaily (Feb.
Predominantly speaking, renewable energy is more expensive than traditional sources and it's not yet efficient enough to be a worst contributer to our energy needs. See http://www.renewableenergy101.info for more info.
