IMEC Collaborates With Cytec On Organic PV

Cytec Industries Inc., a developer of specialty chemicals and materials, and IMEC, a Europe-based independent nanoelectronics research institute, have agreed to work together to develop a commercially viable technology for organic photovoltaic devices with enhanced stability and extended lifetime.

Over the last few years, worldwide research on organic solar cells has mainly focused on increasing the conversion efficiency. However, according to Cytec and IMEC, the operational lifetime of organic solar cells must be improved to extend beyond five years.Ă‚ This challenge is the basis of the collaboration.

To reach this goal, 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. 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 project, which is co-sponsored by the Institute for the Promotion of Innovation by Science and Technology in Flanders, Belgiumwill run for two years and will end in March 2011.
