Abstract

The invention provides a glass and a preparation method thereof. The glass comprises a toughened glass base layer, a substrate coating, a film photovoltaic cell layer, an anti-fouling protective layer and a lead, wherein the substrate coating, the film photovoltaic cell layer and the anti-fouling protective layer are sequentially formed on the toughened glass base layer, and the lead is arranged on the film photovoltaic cell layer; and the substrate coating is used for improving the adhesiveness of the film photovoltaic cell layer on the toughened glass base layer and preventing sodium ions in the toughened glass base layer from being diffused to the film photovoltaic cell layer. By sequentially forming the substrate coating, the film photovoltaic cell layer and the anti-fouling protective layer on the toughened glass base layer serving as a substrate, the obtained glass has good heat insulation performance, light transmittance, anti-fouling performance and the like; and the film photovoltaic cell layer effectively utilizes solar energy for generating power to provide energy for automobiles and the like so as to reduce the oil consumption of the automobiles and the like.

Description

technical field [0001] The invention relates to a glass and a preparation method thereof. Background technique [0002] As one of the many parts of the car body, automotive glass plays an extremely important role in the field of automotive technology. For a long time, researchers have been researching and developing automotive glass from the perspectives of automotive safety and appearance, but rarely from the perspective of using natural resources to generate energy through automotive glass and providing it to vehicles to reduce vehicle fuel consumption. Research has been done with glass. [0003] In automobiles, by installing low-energy (Low-E) glass with thermal insulation performance, it can improve the coldness in winter and heat in summer, reduce fuel consumption, and its good optical performance can prevent glare, so that drivers can drive It is not affected by glare, thereby improving the safety performance of the car. In addition, the use of film (such as the sol...
