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.

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.

ETFE is a kind of fluorine-containing polymer thermoplastic material, the chemical name ethylene tetrafluoroethylene copolymer, in the 1970s, by the United States NASA and DuPont company jointly developed, and applied in the field of space. Because ETFE has strong light transmission and heat insulation, it is soon widely used in various 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.

Zhong Baoshen: "There will be no simple roof in the future. The roof of the future building must be the roof that can generate electricity and save energy." "The 14th Five-Year Plan period is a key period for rural revitalization and the replacement of traditional farm houses with modern buildings, and also a window period for the popularization of green buildings in rural areas."

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.

Building curtain wall is the medium of building and external environment partition and contact, is an important part of building and external energy exchange and transmission.
