The invention belongs to the field of solar energy technology, and discloses a low-emissivity coated glass, and a preparation method thereof. The low-emissivity coated glass comprises a glass substrate and a film stack arranged on at least one surface of the glass substrate; the film stack comprises n groups of laminated film layers, and a Si3N4 film on the outermost film layer of the n groups oflaminated film layers; each group of the laminated film layers comprises a SiO2 layer, a SiONx layer, a Si3N4 layer, a SiONx layer, a SiO2 layer, and a SiONx layer successively from the side close tothe glass substrate and the side far away from the glass substrate. The low-emissivity coated glass possesses low emissivity on certain light wave bands, relatively high visible light transmissivity,and relatively excellent film layer stability, and is suitable to be used in building doors and windows, curtain walls, and photovoltaic assemblies. 本发明属于太阳能技术领域，公开了种低辐射镀膜玻璃及其制备方法。本发明所提供的低辐射镀膜玻璃，包括玻璃基底以及位于所述玻璃基底至少个表面的膜堆，所述膜堆包括n
