The mixture of organic semiconductor electron donor poly(3-hexylthiophene) (P3HT) and acceptor [6,6]-phenyl- C60-butyric acid methyl ester (PCBM) is dissolved in chlorobenzene for measuring the solute particle diameter. By comparing the performance of solar cells and the surface morphology of the active layer, the dispersion law of the mixed solutes in chlorobenzene is analyzed. The influence of temperature and concentration on particle size, furthermore, the impact of particle size on device performance are discussed. The results show that most of the particle sizes in the solution are populated at about 4000 nm, and both the concentration and the temperature of the solution have a significant effect on the particle size of the solution. For low concentration solution, the particle sizes are greatly influenced by temperature. On the contrary, the effect of temperature on the particle size in the solution concentration is less apparent when the concentration becomes higher. When the solution concentration reaches 12.67 mg/mL, it has a preferably dispersion and optimal fill factor. When the concentration reaches 19.00 mg/mL, the solar cell made by the solution shows a well property on power conversion efficiency and short-circuits current.
