Morphological characterization of various PDINO, TiOx, and PDINO:TiOx blend films

Morphological characterization of various PDINO, TiOx, and PDINO:TiOx blend films processed on top of PBDTTT-C-T:PC71BM. Clearly, the PDINO:TIOx blend bearing a ratio of 60:40 yielded the most homogeneous topography, in good agreement with the performance maximum.
