The selective diffusion of small molecules into the amorphous domains of semi-crystalline polymer films is used here to probe the complex morphology of all-organic photovoltaic films. In this case, the ALD precursors of ZnO diffuse into poly(3-hexylthiophene-2,5-diyl):phenyl-C61-butyric acid methyl ester (P3HT:PCBM) BHJs and spatially map the distribution of P3HT amorphous and crystalline domain, and probe the distribution and miscibility of PCBM and P3HT.
