February 23, 2011 — Varian Semiconductor Equipment Associates, Inc. (NASDAQ: VSEA) launched its Solion photovoltaic (PV) ion implant platform into the Chinese market at the SNEC PV Power Expo 2011. Varian said it has partnered with several leading Chinese PV manufacturers to insert Solion patterned ion implantation into volume manufacturing by mid-year.
Varian has established engagements with over seven Chinese PV manufacturers interested in using Solion for manufacturing high-efficiency solar cells with precision and control, and simplified processes. Solion enables solar module manufacturers to achieve a combination of increased cell efficiency at lower production cost by replacing traditional diffusion doping processes with ion implant. In addition to greater precision and process control for improved junction quality, this approach eliminates multiple production steps, improves cell uniformity, and enables significantly tighter binning.
Early Solion users have already adopted the enabling patterned implant technology to produce crystalline solar cells in volume with conversion efficiencies over 19%. Patterned implantation provides a clear roadmap to efficiencies of 22% at reduced cost per watt.
Solion is a development based on Varian’s VIISta product line, which has over 1,200 units in the field. However, Solion is a completely new platform that reflects the needs and priorities of PV module producers, including the innovative ability to perform patterning and doping in a single step using proprietary Precision Patterned Implant (PPITM) technology.
Varian will be exhibiting at SNEC PV Power Expo in Shanghai from February 22 – 24, at booth number 215 in Hall number 5.
Varian is a supplier of ion implantation equipment used in the fabrication of semiconductor chips and photovoltaic modules. More information can be found at www.vsea.com
