Microstructure and local energy transfer of organic photovoltaics
The performance of organic photovoltaics crucially depends on the local polymer organization. By employing 2D POLarization IMaging we can reveal the microstructure of bulk heterojunction all-polymer blends as well as of thin conjugated polymer films prepared by the floating film transfer method . Localized correlations of several 2D POLIM parameters allow for retriving the local polymer chain organisation within the liquid spread polymer film.
