“Blackest” Solar Cell Ever Designed Absorbs 99.7 Percent of All Light
Natcore Technology scientists have created a black silicon solar cell with an average reflectance of 0.3%, making it the “blackest” solar cell ever designed. Compared to the most efficient solar cells currently on the market, Natcore’s development offers a tenfold decrease in reflectance over the solar spectrum. The result is an increase in energy efficiency that could help solar power compete even more effectively with traditional fossil fuels. […]

Solar cell breakthrough taps previously unused energy source
A scientific breakthrough by researchers at the Massachusetts Institute of Technology(MIT) has produced a new type solar cell capable of absorbing energy from the infrared spectrum, where about 40 percent of the energy in sunlight exists.
All prior solar cells ignored the infrared spectrum for energy stored in visible light, but the new cell uses purified carbon fibers converted into microscopic tube-like structures called nanotubes to capture the hidden power. Details of the new cell were published in the latest edition of the scientific journal Advanced Materials.
A bonus: Researchers said that because the cells are transparent, they could one day be laid on top of currently existing solar arrays, turning the less-efficient and more common photovoltaic cells into hybrids capable of much greater energy output.
Of course, ‘solar energy isn’t feasible’ will still come dribbling out of the mouths of big oil….
