According to our research, solar energy accounted for about 60 million ounces of silver demand in 2014, or about 6 percent of total demand. And that number was expected to rise to 15 percent of the total demand by 2018. Eventually, that demand will be removed from the market if and when Natcore's technology is adopted by industry and the adoption could be very swift, as Natcore has no interest in manufacturing solar cells and entering that ultra-competitive battleground for market share. Rather, the company's business model revolves around licensing the technology to any and all comers, earning a royalty on manufacturing equipment, materials, and most important -- each solar cell produced.
