Researchers in Finland have reportedly developed a next-generation solar panel utilizing silver nano particle antennas to trap incoming solar light.  The silver nano-antennas reportedly drastically increase photovoltaic cell efficiency (the percentage of incoming solar light converted into electrical energy- approximately only 20% in current solar panels), and new fabrication techniques allow printing the silver nano-antenna at a low cost. 

Jeffery Christian and the CPM Group’s dire predictions notwithstanding, it appears silver’s industrial demand won’t be decreasing anytime soon.
