centrotherm photovoltaics AG has won two iF product design awards 2012 for its photovoltaic key equipment “c.FIRE” und “GP ISO-TEST. Waf”. Both products, the “c.FIRE” fast firing furnace and the wafer inspection tool “GP ISO- TEST.Waf”, impressed the international jury not only with their outstanding design but also with their functionality, innovation and environmental sustainability.
The “c.FIRE” fast firing furnace, in which the front and rear contacts are burned into wafers at high temperatures, is the latest generation of the established fast firing furnace and is characterized by its compact design. Besides this footprint, the installation and maintance systems have been further optimized in order to reduce the operating costs for solar cell producers. Volatile organic compounds (VOCs) that arise during the burning process were also taken into account: VOC treatment was fully integrated into the restructured housing, thereby enabling any solvents that are emitted to be fed back on a reliable and energy- efficient basis.
The new “c.FIRE” fast firing furnace also impressed a Taiwanese customer. Within a few weeks the equipment was installed, ramped-up and had passed the site acceptance test. The “GP ISO-TEST. Waf” enables the quality control of wafers in the solar cell production. It monitors the insulation resistance between the front and rear side of wafers and enables contributes to the reduction of manufacturing costs in mass production. The design unifies cost optimized production and longevity.
