Abstract

The invention belongs to the technical field of photovoltaic materials and discloses synthesis of a perylene diimide asymmetric micromolecule non-fullerene receptor and a method for printing and preparing an organic solar battery. The perylene diimide asymmetric micromolecule non-fullerene receptor is a broad-bond gap Al-D-A2 type asymmetric non-fullerene micromolecule receptor based on a bridgedunit carbazole core, and has a structural formula I as shown in the specification. The asymmetric micromolecule receptor material which is provided by the invention and is used for printing and preparing the organic solar battery has good solution processing performance and electron transmission performance, and in addition has good absorption complementation and energy matching after being combined with narrow-bond gap polymer donor materials such as PTB7-Th; the receptor can be applied to an open circuit voltage which is 0.95V at most, and energy conversion efficiency which is about 2.01-3.27%, and the broad-bond gap asymmetric non-fullerene micromolecule receptor provided by the invention has wide application prospects in the field of organic photovoltaic.
