Issue Date: | 2011 | Publisher: | WILEY-BLACKWELL | Source: | MAGNETIC RESONANCE IN CHEMISTRY, 49(5). p. 242-247 | Abstract: | PCBM or [6,6]-phenyl-C-61-butyric acid methyl ester is nowadays still one of the most successful electron acceptors for plastic bulk heterojunction (BHJ) photovoltaic devices. In this study, a set of complementary techniques, i.e. solid-state NMR, XRD and DSC, is proposed as a fast and sensitive tool to screen themorphology of PCBM specimens with different preparation histories. Based on proton NMR relaxation decay time values, an interval can be derived that situates the average crystal dimensions and which can further be refined on the basis of XRD patterns and DSC thermograms.
