BERGISCH GLADBACH, Germany, Dec 09, 2010 (BUSINESS WIRE) -- Bruker Energy & Supercon Technologies, Inc. (BEST) and PVA TePla AG (PVA) announced today that they have signed a cooperation agreement on the joint development of a more efficient monocrystalline Si-growing process for photovoltaic (PV) applications.
The innovative concept is based on the application of the strong magnetic field produced by a novel type of superconducting crystal growth magnet (SC-CGM) under development at BEST, and designed specifically for PV applications. The SC-CGM is expected to be integrated with a crystal puller at PVA TePla's Competence Center for Industrial Crystal Growth (CCIC) in Wettenberg, Germany.
Today, the efficiency of solar cells is often degraded by too high of an oxygen content in the crystal structure. The oxygen stems from the Si-Oxide which is used in the crucible wall of the growing furnace for the so-called Czochralski process. The application of a magnetic field along with special process control is expected to dampen the melt flow and thus the transport of oxygen to the crystal, enabling a more homogenous crystal lattice.
Dr. Detlef Krischel, the Managing Director at BEST responsible for the SC-CGM product line, explained: "The goal of our cooperation with PVA TePla is to demonstrate the increase in solar cell photovoltaic conversion efficiency, which has been predicted by computer simulations, along with achieving a stable yield of crystal production. We believe the planned novel magnetic field characteristics will allow us to better control process parameters, which are key for a high productivity Si-growing process."
PVA Crystal Growd Systems的部门经理Michael Volk先生补充说：“我们相信，强大的磁铁与我们的拉杆集成将使我们能够根据强大的水晶增长过程为客户提供改进的交钥匙系统。我们也可以为客户提供。相信，稳定产量的太阳能电池的效率更高将有助于光伏行业降低光伏模块的整体成本。”
最好的and PVA TePla expect first results from their cooperation in the spring of 2011.
