Mr. Erik Oldekop, the spokesman of Nanosolar
said: “We are capable of coating large areas within
very short cycle times”. The factories have already
been built and series production is about to take
off. Nanosolar wants to manufacture its cells in a
430 MW plant in San José, California. These will
then be processed into circuit modules at
Luckenwalde near Berlin.
