Preparation method of p-type CuGaO2 transparent conductive film
The invention discloses a preparation method of a p-type CuGaO2 transparent conductive film, and belongs to the technical field of semiconductor materials. The method comprises the steps: with Inorganic copper salt and inorganic gallium salt as raw materials, a strong base as a precipitator, alcohols as a reducing agent, and sulfonic acid anions as a surfactant, synthesizing CuGaO2 nano-particlesby adopting a hydrothermal method; dispersing the CuGaO2 nano-particles in an organic solvent by using an ultrasonic technology to obtain a faint yellow nano dispersion liquid; and then forming a filmthrough the processes of spin coating, spraying, blade coating and the like, and carrying out low-temperature annealing treatment to prepare the CuGaO2 transparent conductive film. The nano dispersion liquid prepared by the invention has the advantages of high dispersion concentration, high transmittance, high purity and low possibility of agglomeration. According to the preparation method, the problems of complex process, expensive equipment, high preparation temperature and the like of a traditional synthesis method of a CuGaO2 film are solved; the high-quality CuGaO2 film is prepared fromthe nano dispersion liquid, the light transmittance is greater than 75%, the resistance is 500-5000 ohm/square, and the CuGaO2 film can be widely applied to devices such as solar cells, light emittingdiodes and photoelectric detectors.
