While in the past the polysilicon was manufactured almost exclusively for the semiconductor industry, now more than half of the market is devoted to the solar industry. The different alternative routes to purify silicon for photovoltaic applications are presented in the paper, analysing their advantages and drawbacks. Emphasis is made on the CENTESIL initiative, a new private-public partnership venture promoting a pilot plant that is in an advanced state of construction. The goal is to allow the photovoltaic companies worldwide to count with an independent research centre to help them to establish their own polysilicon plant. date_type: published date: 2010 place_of_pub: Stäfa, Suiza event_title: 12th International Conference on Modern Materials and Technologies, CIMTEC 2010 - 5th forum on new materials part C event_location: Montecatini Terme, Toscana, Italia event_dates: 06/06/2010 - 18/06/2010 event_type: conference institution: Telecomunicacion department: Electronica2 refereed: TRUE isbn: 9783908158592 book_title: Proceedings of the 12th International Conference on Modern Materials and Technologies, CIMTEC 2010 - 5th forum on new materials part C official_url: http://www.scientific.net/AST.74.99 citation: Cañizo Nadal, Carlos del and Coso Sánchez, Gonzalo del and Luque López, Antonio (2010).
