This invention discloses a class of water / alcohol-soluble porphyrin organic photovoltaic interface materials, their preparation methods, and applications. The invention uses a porphyrin ring as the core, introducing a benzene ring with an alkoxy chain, along with highly polar pyridine and phosphate groups at the Meso site. The synergistic effect of the alkoxy and polyethylene glycol side chains and the highly polar groups not only endows the material with excellent water / alcohol / polar solvent solubility (without the need for acidic co-solvents), but also acts as a "physical isolation zone" to prevent excessive disordered aggregation in solution. Simultaneously, peripheral pyridine groups with potential coordination activity are introduced, and for the first time, phosphonic acid, possessing a highly polar and ultra-strong inorganic surface covalent anchoring ability, is introduced. The invention reveals the decisive influence of the presence or absence of a central zinc ion on the mechanism of porphyrin molecules anchoring ZnO surface defects, and the law governing the regulation of intramolecular energy levels and macroscopic photovoltaic performance by the number of highly effective anchoring groups.
