| 英文摘要 | In recent years, the development of perylene diimide derivative (PDI)-based non-fullerene organic solar cells has been extensively studied. These solar cells exhibit unique advantages such as complementary light absorption, tunable energy levels, excellent electron transport properties, and relatively low cost. However, the strong pi-pi stacking between the PDI molecules tends to induce an uncontrolled phase separation structure, large domain size, and an unmanageable mixed phase, leading to severe geminate and non-geminate recombination and restriction of the final power conversion efficiency of the non-fullerene-based systems. In this work, it was found that one of the most important parameters that helps regulate phase structure is the molecular diffusion rate. By tuning the thermal annealing and liquid-solid phase separation and blend ratio, the phase-separated structure could be adjusted. Further, the domain size of blend systems with different compatibilities was regulated by balancing the p-p and charge transfer interactions. In addition, the amount of the intermixed phase was controlled by tuning the solubility parameter difference (Delta delta) between the solvent and the solute. |
