China's PV & Energy Storage Conference Concludes: Technology Breakthroughs Fuel Global Cooperation

Chengdu, China – Nov. 20 (Global Energy Watch) – The 8th China International PV and Energy Storage Industry Conference (CIPESIC 2025), a landmark event in the global renewable energy sector, wrapped up in Chengdu on Thursday. Under the theme "PV and Storage Shining Together, Innovating for the Future," the four-day conference brought over 5,000 enterprises from around the world, securing cooperation deals worth over 33 billion yuan (approximately $4.56 billion) and releasing industry guidelines that signal a new phase of high-quality development for the global PV industry.

For international partners and observers, the conference’s biggest takeaways lie in two pioneering initiatives that address key pain points in the global PV market.

First, the world’s first Quality White Paper on PV Cells was officially launched. This document establishes unified standards for PV cell efficiency, service life, and environmental adaptability – a long-awaited framework for buyers worldwide. "Previously, inconsistent quality benchmarks made cross-border procurement risky," noted a representative from Germany’s Solar Power Europe. "This white paper will significantly reduce transaction costs and boost confidence in PV investments."

Second, the Chengdu Declaration issued at the conference called for an end to "price-cutting competition" that has plagued the industry. Instead, it advocates for prioritizing technological innovation and service quality. The declaration, supported by leading enterprises including Longi Green Energy and CATL (which made the top 100 PV & energy storage brands list released at the event), reflects China’s shift from "volume growth" to "value growth" in the PV sector.

Technological breakthroughs showcased at the conference underscore this transition. Longi Green Energy, a global PV giant, announced two record-breaking achievements published in Nature shortly before the event: its ultra-thin silicon-perovskite tandem cell reached a conversion efficiency of 33.4%, while its flexible tandem cell hit 29.8% – a game-changer for applications like building-integrated PV (BIPV) and portable solar devices.

These innovations align perfectly with the diverse needs of global markets. According to Wang Bohua, Honorary Chairman of the China Photovoltaic Industry Association, European markets prioritize high-end, efficient products, while emerging economies focus on cost-effectiveness – both areas where Chinese enterprises excel. "Our technology is not just about higher efficiency; it’s about adapting to different climates and application scenarios," Wang explained.

The timing couldn’t be better. As the EU strives to meet its net-zero goals under the Net-Zero Industry Act (NZIA), its current PV module production capacity still falls far short of the 30 GW target. Meanwhile, emerging markets like Southeast Asia and Africa are ramping up renewable energy investments. The conference’s emphasis on quality and innovation positions Chinese PV products as reliable partners for global energy transition.

"This conference is more than a business event; it’s a platform for sharing solutions to the world’s energy challenges," said an IEA energy analyst in attendance. With China’s PV industry moving toward more sustainable development, the cooperation opportunities highlighted in Chengdu are set to illuminate the path to a greener future.
