Wake Forest’s Plastic Fiber Solar Cells Doubling Energy Output of Flat Ones

Posted by Ovidiu in Solar Power, Uncategorized on April 10, 2010

Solar cells get efficient as time goes, but there are methods to improve the performance of current ones, made with older technologies. Wake Forest Center for Nanotechnology has just received a patent for a new solar cell technology that can double the energy production of current silicon flat cells at highly reduced costs.

Dye-Sensitized Solar Cells Got Better by Using Ionic Salts

Posted by Ovidiu in Solar Power, Uncategorized on October 14, 2009

Grätzel cells work by using the interaction of a structured semiconductor less than nanometer in size and an organic dye acting as a solar collector. Many tweaks to the Grätzel cells are done at the dye level, but this one is different.

Atlantic City Convention Center Installed 2.4 MW Solar Powered Rooftop

Posted by Cristi in Solar Power, Uncategorized on March 28, 2009

13,400 modules, manufactured by the Chinese company Trina Solar, provide 2,4 MW at peak capacity, equivalent to the needs of 280 American houses. The energy generated will reduce the building’s electricity bills with 25% and in it’s lifetime of 20 years the solar panels will save about $4.4 million.

Your Home`s Excess Heat Could Get Recovered by New Cheap Machine

Posted by Ovidiu in Uncategorized on November 24, 2008

This article doesn’t talk about huge producers of energy, or doesn’t mention the use of any prime matter to create energy, but instead it focuses on recycled one. Ener-G-Rotors, a company based in Schenectady, NY, is developing a heat recycler that can work with lower quantities of heat, under 150°C, unlike those of the competitors, aimed only to the higher-class, industrial energy producing stations.
