IMEC and CYTEC to Extend Lifetime of Organic Photovoltaics

Cytec Industries and IMEC are developing a commercially viable technology for organic photovoltaic devices with enhanced stability and extended lifetime. The research will run for two years and end in March, 2011. the project is co-sponsored by the Institute for the Promotion of Innovation by Science and Technology in Flanders.

The project will be approached from two different angles. First, intrinsic stability issues of organic solar cells will be tackled by stabilizing the nanomorphology of the active material blend. IMEC has already shown that the photo-active blend of conjugated polymers and fullerene acceptor molecules is prone to phase segregation under the influence of time and temperature. To halt this, IMEC and Cytec will join their expertise in chemical synthesis and materials processing.

Concurrently, the ingress of extrinsic degradation sources of oxygen and water vapor will be suppressed by the development of an appropriate barrier, encapsulation technology. The technology solutions will build on Cytec’s core competencies of interfacial engineering and coating technology and on IMEC’s background in organic solar cell processing and analysis.
