Characterization of bulk-heterojunction layers by imaging ellipsometry — •Christian Röling1, Mathias Vaupel2, Kristian O. Sylvester-Hvid3, and Peter H.

Conductive polymers and polymer-fullerene blends are promising materials for OLED and plastic solar cell applications. Blends prepared by two different methods, silk-printing and spin-coating were imaged, characterized and mapped using the spectroscopic imaging ellipsometer nanofilm_ep3se.
The optical characterization of bulk-heteroconjugate layers with imaging ellipsometry offers new information on the thickness distribution and refractive index distribution. Ellipsometric contrast micrographs are useful tools for the layer inspection concerning homogeneity and morphology, especially for the optimization of the coating process.
