Scenario's show that solar energy will on the long term be the most important energy source, provided that the cost of Photovoltaic (PV) modules will be substantially decreased. Low feedstock availability (priced at 35-100 _/kg) is currently jeopardising compliance with the EC White Paper objectives of decreasing module costs from _3/Wp to _1/Wp and reaching 3 GWp PV installed in 2010.
Currently 17% of module costs relate to feedstock. Even though cells will be thinner and more efficient, demand for solar grade silicon (sog-Si) will grow from the current available capacity of 15,000 t/yr to approx. 50,000 t/yr in 2010. A low-cost dedicated sog-Si feedstock source is needed in Europe or growth of total PV industry will stagnate. The "Solsilc Demonstrator" consortium will demonstrate on sufficient scale the working of a new intrinsic low cost metallurgical route to produce sog-Si.
