Center for Materials and Devices for Information Technology Research (CMDITR)Photonics Wiki
This wiki is a reference collection on clean energy, organic photovoltaics, research in photonics, and organic electronics.

The bulk of the collection was created by the Center for Materials and Devices for Information Technology Research -NSF Grant #0120967.

The Photonicswiki is now being administered by the University of Washington Clean Energy Institute (CEI) and is transitioning to the Clean Energy Wiki with the addition of new solar materials, energy storage and grid integration topics. Legacy photonics content will be maintained because there is a productive overlap in and fundamental science and the tools.
