Conductive glass with double anti-reflective film surfaces for thin film solar battery and preparation method thereof

Abstract

The invention relates to conductive glass with double anti-reflective film surfaces for a thin film solar battery and a preparation method of the conductive glass. According to the conductive glass, a metal layer (3) is clamped between a metallic oxide conductive layer (2) and a second metallic oxide conductive layer (4); a first anti-reflective film (7), the metallic oxide conductive layer (2), the metal layer (3) and the second metallic oxide conductive layer (4) are sequentially arranged on the surface at one side surface of a glass base material (1); and a second anti-reflective film (8) is arranged on the surface at the other side surface of the glass base material (1). The metallic oxide conductive layer is prepared on the glass base material through methods such as LPCVD (low pressure chemical vapor deposition) or PECVD (plasma enhanced chemical vapor deposition) and the like; the metal layer is prepared by a magnetron sputtering or thermal evaporation method; the second metallic oxide conductive layer is prepared by a chemical vapor deposition method; and the anti-reflective films are prepared by a sol-gel method. The conductive glass provided by the invention has the advantages of good light transmission, strong conduction, high scattering degree, good film layer structure stability, high cost performance and low preparation cost.
