Finally! Maybe - lets hope! twenty years or soTago i was at a solar technology seminar in Kista, Sweden, and talked to a gou that sugested to build a very large clean room where the different layeras ofa solar cell could be sprayed ina continous process onto passing glass sheets. It would make solar cells in about the same cost as other roofing materials; very cheap electicity. But funding costs of such plant would be very huge. Nice to see something like this finally happen.
