Centre Suisse d’Electronique et de Microtechnique
CSEM,Centre Suisse d’Electronique et de Microtechnique (Swiss Center for Electronics and Microtechnology), founded in 1984, is a private applied research and development center specializing in micro- and nanotechnology, system engineering microelectronics and communications technologies. It offers its customers and industry partners custom-made, innovative solutions based on its knowledge of the market and the technological expertise derived from applied research. The activities of CSEM ‘s Polytronics Center in Muttenz (BL) include polymer LEDs, polymer photovoltaics (OPV) as well as organic field effect transistors.
Projects in the OPV field include SUNFLOWER (EU IP project) on roll-to-roll fabrication of printed OPV tandem cells; Rhein Solar, an interregional initiative to promote excellence in OPV in the Upper Rhine valley, DURSOL a CCEM Swisselectric sponsored project on the durability of PV technologies.
CSEM has unique capabilities to perform automated combinatorial testing of solution processed semiconductors for OPV applications. CSEM has developed several lab systems for device lifetime studies, including a fully automated OLED lifetime tester with temperature control, calcium test setup for barrier permeation testing, peel-off and bend-testers for flexible substrates characterization, as well as an automated system for device encapsulation. Furthermore, additive print processes like ink-jet and gravure printing are developed in order to enable the fabrication of fully solution processed organic optoelectronics systems.
