We investigate the impacts of an increasing PV solar power market share on metals demand and supply.
The companion metals analyzed are In, Ge, Cd, Te, Se, Ag, and As, and the host metals are Zn and Cu.
More In, Ge, and Te may result in mining more Zn and Cu than can be used.
Mining more Zn and Cu may result in extracting more Cd and As than can conveniently be sequestered.
The oversupply of Cu and Zn may decrease their virgin metal prices, and thereby discourage their recycling.
