| Popis: | 25th European Photovoltaic Solar Energy Conference and Exhibition / 5th World Conference on Photovoltaic Energy Conversion, 6-10 September 2010, Valencia, Spain; 1066-1072 Over the past ten years the Photovoltaic (PV) Industry has seen unprecedented growth and PVinstallations world-wide have grown from 250 MWp in 2000 to ca. 7800 MWp in the year 2009. More than 80% of module production in 2010 with estimated installation of 10000 MWp is based on crystalline silicon wafer technology. The paper analyses the availability of solar-grade silicon and gives an overview of multicrystalline and monocrystalline silicon ingot and wafer technology. In addition, the paper examines this technology in the context of a growth scenario worked out by the European Photovoltaic Industry Association (EPIA) that would lead to 12% Solar Electricity in Europe and world-wide of approx. 5% by 2020. Emphasis is placed on further cost reduction potential of the dominant c-Si technology for ingot production – directional solidification and Czochralski technique – and wire saw technology for wafering. The importance of economic material usage and recycling is stressed when continuing along the described high growth scenarios towards 2020. |
