The number of micro-sized PCBM aggregations in P3HT/PCBM blend films was reduced by cooling the solution at 0°C. P3HT aggregated when the solution was kept at 0°C for more than 4h. These P3HT aggregations acted as crystal nucleus, resulting in a network of P3HT nanofibers formation in the spin coated films. Then, after thermal annealing the film at 140°C for 1h, the growth of PCBM micro-size aggregations...
The influences of solvent solubility and solution aging on the crystallization of poly(3-hexylthiophene) (P3HT) films were investigated. The solubility difference rather than the evaporation rate of solvent determined the final morphology and crystallinity of film. Marginal solvents (toluene and xylene) with large solubility difference caused crystalline aggregations in solutions during the aging...
