Rooftop solar panels are photovoltaic (PV) panels that are installed on the roofs of residential, commercial, and industrial buildings to capture and convert sunlight into usable electricity. These panels consist of multiple solar cells made from semiconductor materials, typically silicon, which generate direct current (DC) electricity when exposed to sunlight.

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.

Ultra-thin, flexible solar cells are here! Chinese researchers have developed a technology to smooth the edges of a flexible monocrystalline silicon solar cell that is as thin as paper, 60 microns thick, and can bend and fold like paper.

On May 24, the 16th (2023) International Solar Photovoltaic and Smart Energy (Shanghai) Conference and Exhibition was officially opened to the audience. On the opening day of the exhibition, ready-made goods exploded in popularity. In addition to the photovoltaic industry leaders, Tongwei, Longji, Jinko, Trina ,solarspace and so on joined, attracting more domestic and foreign exhibitors to visit.

POE is usually a random copolymer elastomer of ethylene and high carbon α-olefins (1-butene, 1-hexene, 1-octene, etc.) It is precisely because of its special properties that POE is widely used in photovoltaics, automobiles, construction, cables and other fields.

Jinkosolar will invest $52 million to expand its only manufacturing plant in the United States, with the city of Jacksonville, Florida, approving a grant for the project.

At present, the automation degree of the new photovoltaic module production line in China is relatively high. The specific production process of the module includes: laser slicing, cells welding, stacking, lamination, framing, curing, cleaning, IV&EL testing and other links, and finally packaging into the warehouse, into the market.

Silicon prices are expected to turn negative starting in March, with a monthly decline of about 3.2 percent. Single crystal recharging RMB price dropped from RMB235/KG to RMB225/KG, down by 4.26%; RMB price of single crystal compact material is maintained at RMB220/KG.

Under the path of achieving carbon neutrality, by 2030, the global photovoltaic installed capacity needs to increase to nearly seven times that of 2020, and to further expand to nearly 20 times by 2050. GEIDCO: Under China's path to achieve carbon neutrality, by 2030, photovoltaic installed capacity needs to reach 4 times than 2020 year, and by 2050 it needs to reach nearly 13 times.

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.
