Covestro joins hands with photovoltaic industry chain partners to build a sustainable future for the industry

● Signed a six-party agreement during the CIIE to launch an industrial chain cooperation platform

● Rich solutions help create more recyclable, lighter and higher-performance photovoltaic modules

● Alternative raw materials further empower industry development and move towards a circular economy

Recently, Covestro has cooperated with Suzhou Joly Photovoltaic New Materials Co., Ltd., Zhejiang Deyilong Technology Co., Ltd., Changzhou Juhe New Materials Co., Ltd., Shanghai Institute of Microsystems and Information Technology of the Chinese Academy of Sciences, and COSCO Kansai Coatings and Chemicals Co., Ltd.’s five photovoltaic industry chain leading enterprises and scientific research institutes signed strategic cooperation agreements at the 6th China International Import Expo, officially launching the photovoltaic industry chain sustainable development innovation platform. The cooperation aims to promote collaborative innovation and win-win cooperation between Covestro and photovoltaic industry chain partners. With the help of Covestro’s diversified solutions and solid R&D strength, the green energy industry can practice circular economy from the production process and work together to create A sustainable future for the photovoltaic industry.

Under the guidance of the “double carbon” goal, China continues to promote the reform of industrial structure and energy structure, vigorously develop clean energy, and provides support for the vigorous development of the photovoltaic market. From the perspective of materials, Covestro further improves the application efficiency of the components and uses alternative raw materials in the production process of photovoltaic modules. While meeting the development trends of mainstream applications, it also works with the industry chain to address technical challenges and promote the green transformation of the industry.

Anand Gao, Senior Vice President of Covestro’s Coatings & Adhesives Division Asia Pacific
Khot said: “As the world’s leading material supplier, Covestro is committed to proposing feasible innovative technologies and providing differentiated services. At the same time, we hope to empower the development of the photovoltaic industry and realize a circular economy through full cooperation with customers. Contribute to climate neutrality.”

Rich solutions

As a new generation player active in the photovoltaic industry, Covestro will provide a wealth of material solutions for the launched sustainable development innovation platform to improve component power generation efficiency, reduce weight, extend service life, and help customers develop new products. Multiple differentiated products to reduce carbon footprint. For example:

●
The double-sided coated photovoltaic backsheet using Covestro coating raw materials has a light transmittance of up to 93%, helping double-sided modules to reduce weight by 20% and generate power generation gain of 1.29%. It has good aging resistance and guarantees the module for more than 25 years. service life.

● Photovoltaic low-temperature silver paste polymer solution helps next-generation battery technology improve photoelectric conversion efficiency, achieve low-temperature curing below 200 degrees Celsius, and reduce energy consumption.

● Discovery® bio-based water-based solution can be applied to photovoltaic supporting container-type energy storage boxes, replacing traditional fossil-based oil-based products for box coating, effectively reducing VOC (volatile organic compounds) emissions and achieving more than 20% carbon reduction. row; no need to change the coating process and maintain the original coating efficiency. This is also the first time that Covestro has expanded material applications from photovoltaic modules to supporting energy storage systems.

● The polyurethane composite component frame made of Baydo® polyurethane resin has excellent mechanical properties, and its axial tensile strength is more than 5 times that of aluminum alloy. At the same time, it also has strong resistance to salt spray corrosion and chemical corrosion, and is suitable for installation in coastal and offshore electric fields in high-humidity areas. In addition, as a non-metallic material, the frame can not only reduce the power attenuation of the component, but also does not require grounding. The cost is more competitive in the market than aluminum alloy frames, and the carbon footprint is significantly reduced.

Cheng Xudong, general manager of Suzhou Jolywood Photovoltaic New Materials Co., Ltd., said: “Covestro’s innovative solutions provide us with new opportunities and greater industry development space. We hope that through cooperation, we can optimize technology upgrades and energy efficiency, and create a sustainable future.” Sustained photovoltaic products effectively drive the progress of the photovoltaic industry.”

Liu Zhengxin, a researcher at the Shanghai Institute of Microsystems and Information Technology, Chinese Academy of Sciences, said: “Covestro’s product research and development results and innovation level are among the best in the industry. We will maintain close cooperation with Covestro on issues such as circular economy and zero carbon emissions. , injecting vitality into the photovoltaic field and making continuous efforts for China’s green transformation and social development.”

Covestro hopes to help photovoltaic industry chain partners create higher value-added, lower-carbon products through alternative raw materials and more sustainable production processes, achieve more cutting-edge technologies, and promote the sustainable development of the industry and society.
