The Chinese have been using low-purity iron ore (for steel constructing) and low-purity lithium (for batteries) and suffering the consequences of poor finished products..But bullion-grade silver has been long perfected..and respected as a monetary-asset since Adam was a boy. China knows it has to lift it's game & reputation..If they want to compete effectively (long term) in the solar/panels industry they'll have to use the best ingredients..or find a way of using silver more productively..less of it..But either way that results in exponential growth in the number of solar-panels creating our electric-power..and higher demand for silver accordingly. Copper will do well in Electric Vehicles & graphene in other applications..but for photo-voltaic uses nothing comes near to silver and the World will need much more of it

There's good reason why it's called a precious metal
