The invention discloses a preparation method and application of an expanded pi-conjugated metal naphthyanine derivative, and belongs to the technical field of organic photoelectric materials. The naphthyanine derivative can be used as a hole transport material to be applied to a perovskite solar cell. The metal naphthyanine derivative is a planar macrocyclic aromatic compound and has a high pi-conjugation characteristic. By introducing alkenyl or alkynyl to the periphery of the naphthyanine ring, a pi-conjugated system of the molecule can be further extended, so that the charge transport property is improved. Besides, the solubility, hydrophobicity, film-forming property and other properties of the material can be regulated and controlled by changing the type and number of substituent groups on double-bond or triple-bond carbon atoms, so that the requirement of the metal naphthyanine derivative as a hole transport material is met. The hole mobility and the thermal stability of the naphthyanine derivative are far higher than those of original Spiro-OMeTAD. When the naphthalocyanine nickel hole transport material taking alkenyl as a peripheral substituent group is applied to a perovskite solar cell, the photoelectric conversion efficiency greater than 24% is obtained.

The invention discloses an imide metal naphthyanine derivative as well as preparation and photovoltaic application thereof, and belongs to the field of perovskite solar photovoltaics. The metal naphthyanine derivative forms a larger pi conjugated system, and the pi-pi interaction between molecules can be enhanced by the extension of pi conjugation, so that the charge transfer capability is favorably improved. According to the Lewis acid-alkali theory, molecules containing electron-donating atoms such as nitrogen and oxygen can be used as a passivator to reduce defects in perovskite. According to the invention, an imide group with multiple coordination sites is introduced to the periphery of naphthyanine, and the obtained derivative is used as a passivator to be added into a perovskite thin film in a bulk phase doping manner, so that not only can non-coordinated ions (such as Pb < 2 + >) be efficiently passivated, but also the perovskite crystallization process can be regulated and controlled. Finally, the method is beneficial for forming a perovskite active layer with better crystallinity, larger grain size and more uniform morphology, and higher photoelectric conversion efficiency is obtained.
