Renewables Growth Fuels Demand for Min-Metals

Spectrolab, Inc., a wholly-owned Boeing subsidiary, last week realized a PV milestone by producing a solar PV cell with 40.7% conversion efficiency. Partly funded by the U.S. Dept. of Energy, the breakthrough development could bring installed solar PV costs down to $3 per watt and produce electricity at a cost of $0.08 to $0.10 cents per kilowatt-hour, according to an ACORE news report.
