What are photovoltaic materials? The materials used to produce solar panels or cells that convert sunlight into electricity are known as the photovoltaic materials market. These materials are primarily semiconductors that absorb light and convert it into electrical charges. Perovskite, organic and silicon-based photovoltaic materials are the most widely used types of photovoltaic materials. Silicon-based photovoltaic materials dominate due to their efficiency, reliability and proven production methods. However, new technologies such as perovskite solar cells are beginning to emerge as possible industry game-changers because they can deliver higher efficiencies at a cheaper cost. Traditional solar panels are not the only photovoltaic materials on the market. The uses of solar energy are also expanding thanks to advances in solar thin films, bifacial solar cells and building-integrated photovoltaics (BIPV).

Perovskite is A material with a unique crystal structure, originally found in natural minerals, and now generally refers to a class of compounds with the structure of ABX3, where A is usually an organic cation, B is a metal ion, and X is a halogen anion. This structure gives perovskite materials a series of excellent photoelectric properties, so that they show great application potential in the field of solar cells. Perovskite materials can adjust the band gap by changing the composition of the material, and then regulate the wavelength range of the light absorption, and maximize the utilization efficiency of sunlight. It is precisely because of the adjustable band gap of perovskite materials, when constructing solar cells, perovskite materials with different band gaps or perovskite materials and silicon-based materials can be composed of laminated structures to improve the overall light absorption efficiency. In addition, perovskite materials can be prepared at low temperatures by wet process such as solution method, and the preparation cost is also low. As a representative of the third generation solar cells with low cost and high photoelectric conversion efficiency, perovskite solar cells have great application potential.

Solar PV ribbon are an important part of every mainstream solar panel for interconnecting solar cells and providing connection with junction boxes The photovoltaic wire is a tin-plated copper strip with a width of 1-6mm and a thickness of 0.08-0.5 mm and a coating thickness of 10-30 μ m .

Lightweight photovoltaic transparent front plate encapsulated components Currently, the front plate materials of lightweight photovoltaic modules on the market mainly include soft glass, ETFE (ethylene-tetrafluoroethylene copolymer), PVDF materials, etc.

Currently, the photovoltaic solar module industry is undergoing a transition period from PERC technology to N-type technology. N-type cells represented by TOPcon have begun to enter the mass production stage of explosive growth. This transformation has put forward higher requirements for the performance of the encapsulation film of photovoltaic modules. Photovoltaic film encapsulation materials are used between the solar glass/backsheet and solar cells. Their main function is to protect the solar cells, ensure that the photovoltaic modules are not affected by the external environment during operation, and extend the service life of the modules.

In the PV solar panels production, one important process is the backsheet frame sealing and the junction box sealing. We always used the good performance silicone sealant for PV modules encapsulation. If this work not done well, what will be impact ?

POE has good elasticity, strength, aging resistance, weather resistance, and water-proof properties. Its traditional application areas are mainly in automotive parts. Photovoltaic-grade POE is mainly used for photovoltaic components, especially in the packaging of TOPCon, HJT, and perovskite.
