$7.2 billion dollar thin-film photovoltaics market predicted

New NanoMarkets Report Predicts $7.2 Billion Thin-Film Photovoltaics Market by 2015


Apparently, there's a new type of solar panel on the market called "thin-film photovoltaics" (TFPV) , and the market for them is supposed to grow by over 7 times in the next 8 years according to a new report from NanoMarkets.
Just so that everyone is straight, these TFPVs are cheaper, lighter, and more flexible than conventional photo-voltaic panels (aka solar panels). They can also be applied to walls, roofs and windows, and work even in low light, unlike solar panels. This sounds absolutely incredible, with all kinds of possibilities for reducing greenhouse gas emissions and reducing strain on the electric grid.

And if you have $3,000 to spare, I'd love to read the full report on the future market for thin-film photovoltaics.
