This invention discloses a side-chain modified non-fullerene acceptor material and its application in ternary planar heterojunction organic solar cells, relating to the field of organic optoelectronic materials and devices. The side-chain modified non-fullerene acceptor material is designed and synthesized through a side-chain engineering strategy and can be used as a third component in ternary planar heterojunction organic solar cells. This material is highly compatible with classical planar heterojunction systems (such as PM6 / Y6). By adding it to either the donor or acceptor phase, the interfacial energy levels of the active layer can be finely controlled, and the vertical alignment and crystallinity of molecules can be optimized, thereby synergistically improving the photon capture efficiency and charge transport performance of the device. This invention provides an effective material strategy for resolving the contradiction between photon capture and charge transport in planar heterojunction devices, offering a new approach for developing high-efficiency, low-energy-loss ternary organic solar cells.
