Efficiency Boost Should Make Solar Cheaper

Solar energy could become more affordable following a technological breakthrough. Scientists at Australia’s University of New South Wales have boosted the efficiency of solar cell technology, potentially dropping the price of an installed solar system for an average house from around $16,500 to $12,000. (Tax breaks and other incentives would reduce it further.) Currently, up to 45 percent of the cost of solar cell technology is due to the high cost of the silicon used to convert sunlight to electricity.

Now, researchers at UNSW’s ARC Photovoltaics Centre of Excellence, led by PhD student Supriya Pillai report a 16-fold enhancement in light absorption in 1.25-micron thin-film cells for light with a wavelength of 1050 nm. They also report a seven-fold enhancement in light absorption in the more expensive wafer type cells light wavelengths of 1200 nm. The breakthrough is reported in the upcoming issue of the Journal of Applied Physics.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
