Th is is good news. There are several companies very active in the CIGS field now (Nanosolar, Miasole, Konarka, Heliovolt) and there is a very useful directory here.
The premise is simple: thin film solar generates DC current in useful amounts, and the films themselves are produced via a printing process akin to newspapaer printing. That is: by the hectare. The films can be molded in any shape, stuck to existing e.g. roofs, and costs are predicted to ba around $USD0.50/watt within 5 years.
So instead of building centralised power stations, this holds out the prospect of completely self-powered houses. Nice thought, huh?
Another good directory here. Once this stuff gets commercialised with distributors, franchisees, integrators and tradespeople on tap, it will be gangbusters. Or even, Dambusters. Just think of what evacuated-tube solar hot water is doing right now. The same, squared, will apply to residential solar. And the nicest aspect (no URL, found the info while wwilf'ing) is that the power is clean: no more spikes or ripples caused by neighbours welding, nearby industries, or incompetent power suppliers.
