The density field distribution of (a) PCBM, (b) additive and (c) P3HT when XS/A = 0.33. (d) The RDF (radial distribution function) of the moiety F(PCBM)-A(additive) and the moiety P3HT-A(additive) when XS/A = 0.33; g(r)_F-A shows lower value than g(r)_P3HT-A, which indicates that the additive distributes mainly in PCBM region. The selective solubility of additive towards PCBM enhances the phase separation and the device performance.
