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 [1]. Localized correlations of several 2D POLIM parameters allow for retriving the local polymer chain organisation within the liquid spread polymer film.
