Abstract

The invention discloses an AZO transparent conductive film paint, glass plated with the paint and preparation methods thereof. The paint consists of a nano zinc oxide crystal doped with one or more metal ions selected from aluminium ion, tin ion, copper ion, molybdenum ion, titanium ion, vanadium ion, cerium ion, yttrium ion and magnesium ion. A surface of regular glass or ultra-white float glass is plated with the paint through an electrostatic spraying to form a transparent conductive film, so as to obtain an AZO glass, which can be arranged on a solar film cell and a flat-panel display. The prepared transparent conductive film has high conductivity, high transmittance, controllable haze and strong aging resistance capability.

Description

technical field [0001] The invention relates to glass transparent conductive film paint, glass coated with the paint and their preparation methods, belonging to the field of conductive film for solar cells. Background technique [0002] With the depletion of the world's petroleum energy and the energy status of nuclear energy reduction, the utilization of solar energy has increasingly become the main source of future energy. Since solar energy is an inexhaustible, inexhaustible, clean, environmentally friendly and renewable new energy, solar energy Batteries have become one of the most extensive and effective ways to utilize solar energy, and the development of new solar cells has become a new hot spot, especially the research and application of thin-film batteries, which is the development trend of solar cells in the future. [0003] Transparent conductive (TCO) glass is one of the main materials of thin-film solar cell modules. As the front electrode of thin-film solar cel...
