Over at Truck and Barter Ian cook has a post on a new nanotech solar achievement. This company claims to have used nanotech’s self-organizing properties to get the cost of generating power using solar energy to 5 cents per kilowatt hour.
I hope that this breakthrough is robust. Another solar nanotech entrepreneur is Konarka, which is focusing on thin film polymers.
I would be interested to know if that 5 cent per kwh estimate takes into account that nanotech solar only produces electricity at 7-10% efficiency.
