rapid growth of solar technology in the mid- 2000s made ​​us to address the problems of obtaining not only defect-free crystals, but also high quality raw materials. One of the most important goals for us has always been the availability of raw materials, both in terms of quantity and in terms of prices. In 2007 our research and production team approached to the use of electron beam technology for silicon feedstock production and achieved considerable success in this direction. Our research and development allowed us to successfully apply method nearly unepxloited before in the semiconductor industry and to shift from laboratory experiments to industrial research.
