In modern products, coated glass often plays an important role. As an invisible conductive layer, the conductive coating on the glass is suitable for high-tech products such as thin-film solar modules, electrochromic glass or liquid crystal displays. The conductive layer in thin-film solar modules can be made of TCO (transmissive conductive oxide) or molybdenum, depending on the module technology. In order to optimize the energy output, more and more people are coating a layer of anti-reflection coating on the front surface of the solar module, thereby greatly increasing the total amount of light reaching the photovoltaic layer.　　 The relationship between increased energy consumption and global warming has become a global issue. Driven by this, the use of low-e glass in the construction and automotive industries has also become more and more important. Low-emissivity glass reflects heat radiation, thereby reducing heat transfer between the building and the outside world and saving heat energy. These coatings are designed to reduce heat transfer to the outside world, while allowing sunlight and heat radiation to enter the interior of the building. The combination of low-emissivity coating and anti-reflective coating provides more possible ways to prevent heat transfer and realizes that there is no heat loss during the process of passing through the glass plate. In addition, more complex coatings such as convertible glass coatings (electrochromic glass) are suitable for controlling light and heat transfer inside buildings.
