The invention discloses a non-
fullerene receptor with synergistic
assembly performance as well as a preparation method and application thereof. The non-
fullerene receptor comprises oligomeric
ethylene glycol side chains which are substituted at different positions and have different lengths. The non-
fullerene receptor is used as a guest component, so that the
active layer (main body) component is dissolved in various non-
halogen solvents, the compatibility and phase separating size and morphology among the
active layer components are regulated and controlled, and the dependence of the
active layer on low-boiling-point and high-
toxicity halogen-containing solvents is reduced. In addition, the object non-fullerene receptor can regulate and control the
crystallization kinetics of the subject in a high-boiling-point
solvent through a self-assembled
side chain, the
crystallization time of receptor molecules is prolonged, the overall
crystallinity of the active layer is improved, and the dependence of active layer
processing on a post-treatment process is reduced. The three advantages are combined, the
photoelectric conversion efficiency of the
organic solar cell processed by the high-boiling-point and green
solvent is greatly improved, an annealing process is not needed, the device preparation process is simplified, and the device preparation
energy consumption is reduced.
