Problems solved by technology

In this method, a tin oxide-doped fluorine transparent conductive film is deposited on a static hot glass surface by means of an ultrasonic spray method, and the conductivity and transmittance of the film layer are relatively high, but this method does not involve the preparation of an intermediate shielding layer, and at the same time, the method The sample film layer obtained by this method is not uniform enough and the size is small, so it is not suitable for industrial production
Chinese patent CN101188149 describes a method of co-depositing Ce-doped AZO transparent conductive film on the glass surface by radio frequency magnetron sputtering, and the resistivity is 7~8×10-4Ω cm, the transparent conductive film with an average transmittance of 80-90% in the visible light range of 400-800nm, but the transparent conductive film obtained by this method itself does not have a textured structure, and it needs to be treated with a textured surface before it can be applied to solar cells electrode
The reaction substances involved in this method require instantaneous decomposition reaction at high temperature, which is not easy to control, and the process is complex
