Abstract
The price of photovoltaics continues to fall and installed solar generation capacity doubles every two years. To be competitive with existing fossil generation prices, estimates dictate the solar module price needs to decrease by one half, to $0.50 per peak watt (Wp). The production of solar-grade silicon (SoG-Si) contributes the most to the cell cost. In this communication, we outline the current and future methods for SoG-Si production and use.
