Solar Flux: New Process Lets Companies Crank Out PV Panels: Scientific American

“There’s no material, no element which is rare or toxic in this,” adds physicist Johannes Meier, Oerlikon Solar’s chief technology officer. “Therefore, this is a technology that can span over the whole world and has the potential to go to several gigawatts [of installed capacity] in volume.”

Producing the high-performance solar cells costs about $1.20 per watt of cell capacity, according to O’Brien. “If we can really bring costs down of [photovoltaics (PV)], then you can really bring down the cost of a kilowatt-hour produced by PV and be soon competitive with conventional forms” of power generation, like burning coal, Meier adds. “If that happens, then the market can really explode.”
