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.

Photovoltaic PV frame is one of the important solar materials/ solar component for solar panel encapsulation, which is mainly used to protect the edge of Solar glass,It can strengthen the sealing performance of solar modules, It also make an important affect for the life of solar panels.

In the first half of the year, the total export volume of China's photovoltaic products (silicon wafers, solar cells, solar pv modules) was preliminarily estimated to exceed US$29 billion a year-on-year increase of about 13%. The proportion of exports of silicon wafers and cells has increased, while the proportion of exports of components has decreased.

The photovoltaic front sheet and back sheet are very important for the solar panels encapsulation. In general, the photovoltaic backsheet is mostly PET based polymer materials, while the front plate is mostly photovoltaic glass. Photovoltaic backsheet mainly has three layers, the outer layer is mostly fluorine-containing polymer film, which has good environmental corrosion resistance; the middle layer is PET layer, which has good insulation performance, and the inner layer has good bonding effect with EVA and so on.

The development of photovoltaics has brought great opportunities for the development of chemicals and new materials industries. However, N-type TOPCon and heterojunction cells are more sensitive to water vapor, and POE or EPE films with better water vapor barrier properties are popular, which has led to a substantial increase in the demand for POE. It is estimated that the global PV POE demand will reach 410,000 in 2023 Ton. China still needs to import a large amount of EVA and POE, and domestic chemical companies are actively deploying production capacity.
