Precision and speed are features of a novel high-throughput system for the metallization of silicon solar cells and other functional printing applications. The system is able to realize high-precision coating processes using rotary screen printing and flexographic printing with a throughput corresponding up to 8000 components per hour on an industrial scale. The demonstrator machine was developed by a project consortium under the joint leadership of the ASYS Automatisierungssysteme GmbH and the Fraunhofer Institute for Solar Energy Systems ISE. The new system features a high-throughput transport system, in which the components to be printed, silicon solar cells, are transported on autonomous shuttles with high speed and precision through the rotary printing units of the Gallus Ferd. Finest structures can be printed directly on the components. Depending on the specific requirements, a flexographic printing or a rotary screen printing unit can be used for the printing process. The modular system design also facilitates other printing and coating processes such as multi-nozzle dispensing and gravure printing.
