[0002] Single-silver glass, that is, single-silver Low-E glass, is a low-emissivity (Low-E) glass with a single-layer ultra-thin silver film coated on the glass surface. According to different light transmittance and sun-shading performance, single-silver Low-E glass can be divided into high-transmittance Low-E glass and sun-shading Low-E glass. High-transmittance single-silver glass has a good visible light transmittance, making the indoor light bright, the field of vision open, and the daylighting effect better. However, the visible light transmittance of the existing single-silver Low-E glass can only reach about 80%, still unable to meet the requirements of customers for higher transmittance.

[0003] Chinese Patent CN 212199019 U discloses a high-transmittance single-silver low-emissivity coated glass, including a glass substrate layer and a coating layer. The coating layer is successively compounded with eight film layers from the glass substrate layer outwards. The first layer is a SiNx layer, the second layer is a ZnAl layer, the third layer is an Ag layer, the fourth layer is a NiCr layer, the fifth layer is a ZnAl layer, the sixth layer is a ZnSn layer, the seventh layer is a SiNx layer, and the eighth layer is a ZrOx layer; the first layer and the second layer are the first dielectric combination layer, the third layer is the low-emissivity functional layer, the fourth layer is the first barrier protection layer, the fifth layer and the sixth layer are the second dielectric combination layer, and the seventh layer is the film layer protection layer. The utility model has the advantages of high light transmittance, good antioxidant performance, etc. Although the glass disclosed in this patent has the characteristics of high light transmittance and good antioxidant performance, the light transmittance of the whole glass can only reach more than 80%, and the outdoor color is also monotonous colorless.
