What kind of Solar materials are you looking for now ?

On June 10, the 18th (2025) International Solar Photovoltaic and Smart Energy & Energy Storage and Battery Technology and Equipment (Shanghai) Exhibition opened at the National Exhibition and Convention Center (Shanghai). Over 3,600 companies from 95 countries showcased products spanning the entire photovoltaic industry chain. Advanced technologies like TOPCon and perovskite tandem cells, along with integrated photovoltaic - energy storage solutions, were highlights. The event also featured forums on industry trends. Lasting until June 13, this exhibition serves as a crucial platform for global cooperation, innovation, and the push towards green energy transition.

This article focuses on the advantages and disadvantages of double - sided and single - sided coated fluorinated backsheets for photovoltaic modules. Double - sided coated ones offer excellent weather resistance, high mechanical strength, and good compatibility, but they are costly, less environmentally friendly, and heavy. Single - sided coated backsheets have cost and weight advantages, and better environmental performance, yet their weather resistance is slightly weaker, the process is more complex, and market recognition is low. Overall, the choice between them depends on specific project requirements and application scenarios.

Electrical connection materials are crucial components in photovoltaic (PV) modules for achieving current conduction, and their performance directly impacts the module's conductive efficiency, reliability, service life, and safety. The following analysis explores the specific impacts of core materials such as solder ribbons, busbars, and junction boxes on module performance :
