Abstract

The invention discloses a method for preparing textured ZnO transparent conductive coated glass, belonging to the fields of glass finishing and silicon thin-film solar photovoltaic cells. The texturedZnO transparent conductive glass is a key material for realizing integration of photovoltaic buildings and is an important premise for improving the conversion rate of the silicon thin-film solar photovoltaic cells. In the invention, a ZnO transparent conductive coating film is prepared on the substrate of the textured glass, and the textured structure of the ZnO transparent conductive coated film is the same as that of the textured glass. The method comprises the following steps: 1) the textured glass prepared by a calendaring method is taken as glass substrates; 2) a SiO2 isolation transition layer is plated by magnetron sputtering on the surface of the textured glass, and a ZnO thin film is sputtered and precipitated on the SiO2 isolation transition layer; and 3) the structure of the formed ZnO transparent conductive textured film is consistent with the structure of the substrate of the textured glass; the textured ZnO transparent conductive glass wool degree ranges from 10 to 40%,the total transmittance of the visible light is more than or equal to 82%, and a square resistance ranges from 8 to 20 omega/square.
