Nanowire Super Solar Panels Get Funding in Sweden

The Swedish solar startup Sol Voltaics is getting a $6 million conditional loan from the Swedish Energy Agency, Sweden’s national authority for energy policy issues, and is in the process of raising more venture capital, reports Eric Wesoff at GreenTechMedia. Sol Voltaics plans to use gallium arsenide  nanowires to create another absorber layer on top of existing solar cells to extract more light and raise efficiency by 25 percent — an enormous stride, as far as solar efficiency numbers go. This suggests that a 17-percent-efficient crystalline silicon panel has the potential to reach 22 percent efficiency with the addition of nanowires. The nanowires are tiny solar cells about one or two microns long and approximately 100 nanometers in diameter, and they’re sold as an ink-like solution. The layer of nanowires acts like a second solar panel, says CEO David Epstein, and can “capture light very effectively on top of panels using a phenomenon called wave-concentrated photovoltaics (WCPV)… The method we use to make these products is cost-effective with silicon,” he said.  The company expects to have acommercial product in full production by 2016.


Join the swelling numbers of voters TELLING Congress they’ll vote for Clean Energy candidates here: . This is an ongoing campaign (the next Congressional election is in 2 years!) so please, spread the word. It’s our way of telling Congress that a strong clean energy voting bloc is out there. This is how YOU can make a difference.
