Abstract
The cross-sectional morphology of the bulk heterojunction (BHJ) films comprising regio-regular poly(3-hexylthiophene) (rrP3HT) and [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) was observed with transmission electron microscopy (TEM). The cross-sectional TEM images of the BHJ film provide information on the pathways for charge transport through the film thickness. The length scale of the phase separation was obtained from spatial Fourier transform analysis of the TEM images and from calculations of the autocorrelation function.
