Problems solved by technology

The transparent conductive oxide (TCO) thin-film glass used as the front electrode must meet high transmittance, low resistivity, and a certain light-trapping structure to improve the efficiency of a-Si, μc-Si and amorphous silicon thin-film solar cells. Played a decisive role, but in the mass production of TCO glass, due to the constraints of film thickness and resistivity, the light transmittance of TCO glass is low, resulting in the penetration of the overall film layer often cannot be balanced with it

Abstract

The invention discloses a transparent conductive film glass and a preparation method thereof. The transparent conductive film glass comprises sequentially stacked components of a glass substrate, multiple antireflective film layers, and a transparent conductive layer. According to the invention, the antireflective film layers are added between the glass substrate and the transparent conductive layer, such that reflection of lights in the transparent conductive film glass is reduced, and lights are subjected to refraction, such that the light transmittance of the transparent conductive film glass is improved. The preparation method has simple processes. With the method, production efficiency is improved, and production cost is reduced. The method is suitable for industrialized productions.
