Varian Semiconductor Equipment Associates today announced that its Solion ion implantation systems have been widely adopted by manufacturers of PV cells. According to Varian, which provides semiconductor processing equipment, the year-old technology is now being used by more than ten PV manufacturers in the US, China, Taiwan, South Korea and Europe.
The Massachusetts-based company said that a number of its customers were now running multiple systems at full production, and that it had received several repeat orders. Varian’s Solion systems uses ion implantation rather than diffusion-doping to introduce dopants into semiconductor materials, a process that the company claims simplifies the manufacturing process and can increase cell efficiencies to over 19%.
“Just one year ago, Solion was undergoing beta testing and evaluation; today, Solion systems are production proven and processing millions of cells at several of the world’s largest and most advanced PV manufacturers,” said Jim Mullin, the vice president and general manager of solar products at Varian. “This significant market traction and acceptance is a tribute to Varian’s ability to engage with customers, understand their needs, and deliver technology that provides near-term and long-term benefits for increasing cell efficiency and reducing cost.”
Varian is currently exhibiting at the 26th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC) in Hamburg, Germany, and can be found at booth B5/A21.
