LONGi accelerates mass production and collaborative innovation for BC technology
LONGi, a leading developer and manufacturer of back-contact (BC) solar technology, has initiated an effort to establish a Global BC Ecological Collaborative Innovation Center. The center’s core focus would be to advance BC technology through an open innovation ecosystem. On the same day, LONGi signed cooperation agreements with Laplace, Shaanxi Xingbei New Energy Technology Co., Ltd., and Jiangyin Haida New Energy Materials Co., Ltd. to jointly develop BC-related technologies and products.
LONGi stated that it is committed to building a BC ecosystem. As of the end of May 2025, it had formed 55 collaborations with 44 global ecosystem partners and completed 23 technology deployments across the value chain. These deployments cover all BC-related areas, including silicon wafers, cells, modules, system solutions, hydrogen energy, biomass, and engineering technologies.
In a recent roadshow presentation, the company reported a stable monthly output of 2 GW for its HPBC 2.0 cells, with a production yield of 97%. For 2025, LONGi aims to ship 80 GW to 90 GW of solar modules.
Last month, LONGi announced that it will allocate RMB 1.08 billion ($150 million) to its BC cell subsidiary to support the implementation of a 12 GW high-efficiency monocrystalline cell facility (see China Solar PV News Snippets).
Smart energy solutions provider Chint Green Energy plans to establish a new manufacturing base for solar inverters and energy storage products in Sheyang County, Yancheng City, Jiangsu Province. According to local media Sheyang Daily, the Chint Group subsidiary has signed a project agreement with the local government. The manufacturing base will be located in the Sheyang Port Economic Development Zone, with a total investment of RMB 5 billion ($694.44 million). To be built in 2 phases, it will mainly focus on manufacturing inverters and containerized energy storage systems.
Late last month, Chint Green Energy's sister company, Astronergy, received validation of its carbon reduction targets from SBTi, with the company committing to reducing its Scope 1 and Scope 2 emissions by 58.8% by 2034 (see China Solar PV News Snippets).
Wearable and portable PV product manufacturer Ternova has unveiled a series of flexible perovskite-based solar products, including a jacket, a smart wristband, outdoor tents, backpacks, and foldable PV chargers, all powered by solar energy.
Notable among these, the solar-powered jacket integrates foldable solar modules with a total output of 8 W and includes a 10,000 mAh energy storage module, capable of functioning in extreme environments from -20°C to 50°C. The smart wristband features a built-in flexible thin-film solar module that enables real-time outdoor charging and supports standard smart features such as heart rate monitoring, step tracking, and sleep analysis.
The China Chamber of Commerce for Import and Export of Machinery and Electronic Products (CCCME) has called for opposition to unfair competition and promoting the healthy development of foreign trade in the solar sector. The association noted that some enterprises have been exporting PV products at prices below cost, which harms the industry as a whole. It proposes that the solar industry:
Strictly adhere to the principles of fair competition and conduct business operations in compliance with laws and regulations;
Align capacity expansion with actual global market demand and phase out outdated production capacity in an orderly manner;
Focus on technological innovation and quality improvement to shift from “scale-based advantages” to “quality-based advantages”;
Strengthen self-discipline and jointly abide by the Code of Conduct for Foreign Trade Enterprises in the PV Industry.
The Code of Conduct was initiated by CCCME in November 2024 to maintain export order and protect industry interests. It encourages enterprises to comply with laws and regulations overseas and avoid unfair competitive practices. A total of 22 companies, including Trinasolar, JinkoSolar, JA Solar, LONGi, and Tongwei, have signed the agreement.
In a recent meeting with industry representatives and the CPIA, MIIT emphasized the need to curb disorderly and low-price competition through legal and regulatory means (see China Solar PV News Snippets).
Corrigendum: The news inadvertently identified Chint Green Energy as Astronergy. It has now been rectified.
