Harnessing sunlight on the cheap
src

MIT students are developing a prototype for a low-cost concentrating solar power system they think could revolutionize the field. It's a 12-foot-square mirrored dish capable of concentrating sunlight by a factor of 1,000, built from simple, inexpensive industrial materials selected for price, durability and ease of assembly rather than for optimum performance. They believe that in mass production, the dishes can be competitive in cost with other energy sources and could produce heat for space heating and electric power at the same time.

Of Circles and Solar Cells
src

University of Washington researchers have created "popcorn balls" out of nanometer-sized kernels of light-absorbing material to capture more light on solar collectors by clumping hundreds of minuscule grains into clusters of large grains. (University of Washington) The small grains provide a large surface area for maximum absorption, while the large grains are closer to the wavelength of visible light and so ricochet the light into the smaller grains.

Solar Cell Production Jumps 50 Percent in 2007
Source: Earth Policy Institute

Production of photovoltaics (PV) jumped to 3,800 megawatts worldwide in 2007, up an estimated 50 percent over 2006. At the end of the year, according to preliminary data, cumulative global production stood at 12,400 megawatts, enough to power 2.4 million U.S. homes. Growing by an impressive average of 48 percent each year since 2002, PV production has been doubling every two years, making it the world’s fastest-growing energy source.
