This invention discloses a class of porphyrin-based A-D-A type polymer photovoltaic materials, their preparation methods, and applications. The invention utilizes a porphyrin-DPP system constructed through Sonogashira coupling, placing the donor unit at the center of the A-D-A structure. This A-D-A structure more effectively enhances the intramolecular push-pull electronic effect, promoting intramolecular charge transfer and thus significantly broadening and redshifting the light absorption range of the polymer. Furthermore, the A-D-A structure facilitates more ordered and compact intermolecular stacking, promoting the expansion of π-π conjugation and potentially increasing the carrier mobility of the material. This lays the material foundation for obtaining higher short-circuit current densities and fill factors in devices.
