Abstract

The invention provides a preparation method of a metal-doped zinc oxide liquid-phase homogenous-dispersed body. The preparation method is characterized in that zinc salt is used as a reaction source and metal salt is used as a doping source in an alcohol phase system, and on that basis, the metal-doped zinc oxide nano-particle dispersing liquid is prepared by adoptinga low-temperature solution method under an alkaline condition; then a trace of surfactant is added to further improve the dispersing stability and the conductivity. The liquid-phase homogenous-dispersed body is characterized in that the metal-doped zinc oxide particles are wrapped with the surfactant layer, and the one-dimensional size is 10-20nm; the nano-particles are uniformly dispersed in the liquid-phase medium; the concentration of the metal-doped zinc oxide particles in the dispersed body is 10-20mg / mL. The preparation temperature of the metal-doped zinc oxide dispersed body is not beyond 80 DEG C; the preparation process is simple, the energy is saved and the environment is protected; the product is high in stability, high in conductivity, and free from precipitation after standing for more than 3 months; the obtained nanometer material is high in conductivity and has a good application prospect in the field of photoelectric appliance such as the solar cell field.

Description

technical field [0001] The invention belongs to the technical field of metal material preparation. Background technique [0002] Organic solar cells have broad commercial application prospects due to their thinness, flexibility, and ease of large-area preparation in low temperature and non-vacuum environments in product manufacturing. The interfacial layer has the functions of adjusting the energy level, improving the transport and collection of charges, improving the light absorption of the active layer and improving the stability of the device. Therefore, in order to meet the high-performance requirements of social development for solar cells, it is imperative to study the interface layer. Zinc oxide (ZnO) is the most widely studied interfacial layer material with outstanding application value because of its advantages of matching energy levels, high electron mobility, good light transmission and environmental stability, and low cost. At the same time, The high-conductiv...
