MRC -- Covestro has entered into a strategic cooperation agreement with five partners in China's photovoltaic (PV) value chain, inaugurating a new innovation platform dedicated to advancing sustainability within the industry, said the company.
By capitalizing on Covestro's diversified solutions and robust research and development capabilities, this collaboration aspires to facilitate the integration of circular economy principles in the solar power sector's manufacturing phase, ultimately forging a sustainable path forward for the industry itself. This milestone was inked at Covestro's booth during the China International Import Expo (CIIE), an annual event dedicated to promoting imports into China and fostering international trade and cooperation.
The other partners are Jolywood (Suzhou) Sunwatt Co Ltd, Zhejiang Deyilong Technology Co Ltd, Changzhou Fusion New Material Co Ltd, Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences, and COSCO Kansai Paint & Chemical Co Ltd. In alignment with China's "double carbon" goals, the country continues to advance the reform of its industrial and energy structure, dedicating significant efforts to bolster clean energy, notably solar power. Leveraging its material expertise, Covestro plays a dynamic role in PV module production, elevating their efficiency and introducing alternative raw materials.
This approach enables Covestro and collaborators to tackle technical challenges and advance the green transformation of the PV industry itself, while remaining attuned to evolving industry trends. As a fresh and dynamic entrant in the PV industry, Covestro is poised to offer a wide array of material solutions through the newly launched platform. These solutions aim to enhance power generation efficiency, reduce module weight, and extend the service life of PV modules. Meanwhile, they empower customers to innovate and develop new products, all the while contributing to a reduction in their carbon footprint. For instance: Covestro's coatings raw material solution can ensure that two-sided coated backsheets achieve a light transmittance exceeding 93%, enable bi-facial PV modules to reduce their weight by 20% and increase power generation by 1.29%.
Additionally, these modules exhibit outstanding aging resistance, guaranteeing a service life of over 25 years. Covestro's low-temperature photovoltaic silver paste polymer solution, integrated into next-generation cell technology, excels in enhancing photoelectric conversion efficiency. Furthermore, its capability to cure at temperatures below 200 degC contributes to a notable reduction in energy consumption. Decovery, a bio-based waterborne coating raw material, is a viable choice for coating containerized energy storage systems. By replacing conventional fossil-based solvent-borne materials, it reduces carbon emissions by more than 20% and effectively diminishes emissions of volatile organic compounds. Importantly, its application doesn't require any modifications to the painting process, thus preserving work efficiency.
This represents a step forward as Covestro extends its material applications from photovoltaic modules to encompass related energy storage systems for the first time. Polyurethane composite frames for PV modules, made of Covestro's Baydur resin, boast remarkable mechanical properties, featuring an axial tensile strength over five times that of aluminium alloy frames.
We
remind, Covestro is expanding its production capacities for thermoplastic polyurethane (TPU) Films in the Platilon® range, as well as the associated infrastructure and logistics. To this end, the company is investing a low double-digit million euro amount in its German center of excellence for the aforementioned films in Bomlitz, Lower Saxony.
