From November 17 to 20, the 9th China International Photovoltaic and Energy Storage Industry Conference 2026 will be held grandly in Chengdu, China. As one of the important parallel conferences, the Second Photovoltaic CTO Summit and Technological Innovation Conference will be held concurrently. The summit will invite leading global photovoltaic technology experts, academician experts in the domestic photovoltaic field, CTOs of leading enterprises, and other industry leaders to gather in Chengdu. Focusing on innovative technologies such as TOPCon, BC, heterojunction, and perovskite, they will share cutting-edge perspectives, discuss the future of photovoltaics, and bring new value thinking to the industry.

Global Technology Experts Gather to Deeply Analyze Photovoltaic Technology Development Trends

As one of the global barometers for photovoltaic technology trends, the first Photovoltaic CTO Summit in 2025 brought together leading figures such as Martin Green, the "Father of World Solar Energy" and Professor at the University of New South Wales in Australia; Song Dengyuan, CTO of Yito New Energy; Wang Wenjing, Chief Scientist of Huasheng New Energy; Xing Guoqiang, Photovoltaic CTO of Tongwei Co., Ltd.; Ouyang Zi, President of the Product and Solution R&D Center at JA Solar Technology; Xu Weizhi, CTO of Chint New Energy; Chen Yifeng, Vice President of Trina Solar; and Tong Hongbo, Dean of Research Institute No. 1 at LONGi Green Energy Central Research Institute. Through multiple technical speeches and CTO dialogues, they shared insights and sparked wisdom, becoming focal points that garnered widespread attention in the industry. The second summit will be a comprehensive upgrade with an even higher profile. It will invite leading global photovoltaic technology experts, academician experts in the domestic photovoltaic field, and CTOs of leading enterprises to gather in Chengdu. Through high-end technical dialogues and keynote speeches, they will share cutting-edge technology trends and discuss innovative development in photovoltaics.

The Second Photovoltaic CTO Summit will invite Professor Martin Green, the "Father of World Solar Energy," to attend. At the first summit, he systematically interpreted the cutting-edge trends and industrialization bottlenecks of photovoltaic technology, sparking in-depth industry discussions with every judgment he made, from silicon-based routes to back-contact technologies and the future of perovskite.

As we enter 2026, Martin Green's technological predictions are being validated one by one: TOPCon has firmly established itself as the mainstream technology, accounting for approximately 80% of the market, with mass production efficiency continuously advancing towards "25%+"; back-contact technology has undergone a significant leap, with rapidly expanding production capacity; the cost pressure of heterojunction has been systematically alleviated through the large-scale application of low-silver solutions such as silver-clad copper, with high silver prices instead creating a new cost moat for it; while perovskite has repeatedly set new records in laboratory efficiency, its stability bottleneck remains unbroken, and the entire industry is shifting its R&D focus from efficiency pursuit to long-term reliability breakthroughs. The current photovoltaic technology landscape is accelerating its differentiation and reshaping along the path outlined by Martin Green. What latest insights Martin Green will bring in 2026 remains to be seen.

Focusing on Emerging Industry Directions to Create a Global Photovoltaic Technology Event

Currently, the photovoltaic industry is undergoing a crucial transformation from "scale expansion" to "technology-driven value creation." TOPCon remains the mainstream, BC is accelerating its transition, the cost bottleneck of heterojunction is gradually being overcome, and the efficiency of perovskite tandem cells is repeatedly setting new records, with multiple technology routes competing and cooperating in parallel. The industry consensus is becoming increasingly clear: only by continuously investing in technological R&D can one gain a competitive edge in industry development.

This summit will continue to conduct forward-looking discussions on photovoltaic technologies such as TOPCon, BC, heterojunction, and perovskite, while further broadening the scope of topics to focus on emerging directions such as space photovoltaics and future energy development, exploring paths for technological innovation. Whether it's the stringent technical requirements for efficient, lightweight, and radiation-resistant cells in space scenarios or the systemic demand for multi-energy complementarity in future energy systems, these factors will drive the iterative upgrading of crystalline silicon and next-generation photovoltaic technologies. The Second Photovoltaic CTO Summit aims to establish a high-end dialogue platform that not only delves deeply into current mainstream technologies but also forward-looking strategic planning  for future directions, enabling the industry to stay on the main track of photovoltaics while closely following every innovative wave that may trigger transformation.

From November 17 to 20, at the 9th China International Photovoltaic and Energy Storage Industry Conference 2026, the global photovoltaic technology "super brains" will gather once again. We sincerely invite industry colleagues worldwide to join us for this technological event and explore the future of photovoltaics together.
