Solar panel breaks "third of a sun" efficiency barrier

Solar panel breaks "third of a sun" efficiency barrier | Le flux d'Infogreen.lu | Scoop.it

Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity – a goal once branded "one third of a sun" in a Department of Energy initiative. The Amonix module clocked an efficiency rating of 33.5 percent.

 

During a period of testing by the National Renewable Energy Laboratory back in May, a peak efficiency of 34.2 percent was achieved, which Amonix claims is the highest ever reached by a PV module under real-world conditions. However, Amonix is only now drawing attention to the breakthrough, which saw its own record of 30.3 percent efficiency broken.

 

Amonix modules employ concentrated photovoltaics (CPV) technology, which add optical whizbangery such as mirrors and lenses to concentrate more direct sunlight onto individual solar cells. The technology is not to be confused with concentrated solar power, which applies similar optical technology to solar thermal systems which heat water, but also generate electricity with the addition of a heat engine.

The Myth of Affordable Energy

The Myth of Affordable Energy | Le flux d'Infogreen.lu | Scoop.it

Ed Dolan, economist - interview by James Stafford from Oilprice.com

"In my view it is a myth that cheap energy - "affordable energy" as many people like to say is vital to growth. The idea that there is a lockstep relationship between growth of GDP and use of energy is widespread, but the data simply does not bear it out. Instead, what they show is that the world's best-performing economies have become dramatically more energy efficient over time.
(...)
There is only one right way to promote renewables, and that is to introduce full-cost pricing of all forms of energy. Full-cost pricing is a two-part program.

First, it means pricing that covers the full production costs for every form of fuel. No subsidies for anyone—not for oil, not for ethanol, not for wind or solar.

The second half of full-cost pricing is to include all of the nonmarket costs, what economists call the “external costs” or “externalities.” The most publicized of these are pollution costs, whether those take the form of local smog, oil spills, climate change, or bird kills...."
