JENA, Germany, Sept. 13, 2010 — Driven by falling prices for solar cells modules and competitive pressure, the manufacturers of crystalline solar cells are constantly looking for new methods and cell concepts to cut production costs and improve cell efficiency. Jenoptik GmbH Lasers & Material Processing division has developed the Jenoptik-Votan Solas 1800/3600 product family. The internal valued-added chain from the laser sources, the laser systems, the fully automatic laser production machines and real-life test environments for all processes enable Jenoptik to offer an optimum solution to customers. Different processing modules can be integrated to realize all relevant laser processes, including metal/emitter wrap through, selective emitter doping, laser ablation of the dielectric layer, laser edge isolation, laser-fired contacts and thermal laser separation. Depending on customer requirements, a configuration for a research and development system with maximum throughput of 1000 wafers per production day or a fully automatic production machine with more than 3600 wafers an hour can be chosen. In addition to integration in new factories, the system also can upgrade current operational production lines. The service-friendly wafer transportation concept can be adapted to the various transport solutions installed in production lines. Freely selectable options and the modular design provide flexibility.
