Solar PV Materials Demand Doubling in Five Years

Solar PV Materials Demand Doubling in Five Years

AEI's report covers the production processes and supply chain for solar cell manufacturing, including silicon, slurries, gases, wet chemicals, precursors, dopants, and other materials. The group finds, for example, that of the $19.7 billion worth of solar PV materials sold in 2011, polysilicon made up 41 percent of that; next was glass, ethylene vinyl acetate (EVA) films, and backsheets (16 percent), saw wires and slurries (12 percent), metallic pastes (11 percent), various chemicals (9 percent) and other materials in the balance (11 percent). Silicon's percentage of that grouping, though, is seen sinking to just 16 percent by 2016, as solar manufacturers adopt new ways to reduce their usage of the material to start with (kerfless wafering and implants, a la Twin Creeks , Ampulse , SiGen and others) or simply improve their methods of processing it, with diamond wire saws. ...
