At the critical juncture of profound restructuring of the global energy landscape and the photovoltaic (PV) industry stepping into the deep-water zone of technology, a grand technical event gathering top global wisdom is about to kick off. From November 17 to 20, the 9th China International Photovoltaic and Energy Storage Industry Conference 2026 will be grandly held in Chengdu, China. As one of the key parallel sessions of this conference, the 2nd PV CTO Summit & Technological Innovation Conference will be held concurrently. With higher-standard and deeper-dimensional technical discussions, the summit is committed to building an advanced platform integrating cutting-edge insights and strategic collaboration for the global PV industry, helping the PV sector anchor a new direction amid transformations.

Currently, the PV industry is undergoing a historic transformation from "scale expansion" to "technological value-driven" development. It is no longer a simple competition of production capacity, and the core anchor of industry competition is rapidly shifting to breakthroughs in underlying materials, innovation of device structures and optimization of system integration.

In 2026, the PV industry presents a reshaping trend of multiple technical routes competing and cooperating in parallel with accelerated differentiation — TOPCon, HJT, BC, perovskite and tandem batteries each give full play to their strengths, with efficiency records being refreshed frequently. However, practical challenges such as mass production thresholds, stability and cost curves cannot be ignored. At the critical node where the choice of technical routes is intertwined with long-term strategic resolve, how to accurately judge the direction and concentrate resources to overcome difficulties has become a strategic proposition that the whole industry must answer prudently.

Against this backdrop, the 2nd PV CTO Summit & Technological Innovation Conference will focus on the whole chain of PV technological innovation. It plans to invite Professor Martin Green, the "Father of the World's Solar Energy", academicians and experts in the PV field at home and abroad, academic leaders of authoritative scientific research institutions, as well as CTOs and R&D heads of leading PV enterprises to gather in Chengdu once again. They will carry out multiple rounds of in-depth dialogues and exchanges of views around core topics such as "how to break through the efficiency limit", "how to cross the mass production bottleneck", "how to layout emerging scenarios" and "how to realize the transformation from laboratory to industrialization".

In terms of topic setting, this summit will present an unprecedented depth of technical exploration. From the refined iteration path of crystalline silicon passivation technology to the reliability tackling of perovskite/crystalline silicon tandem batteries; from the cost reduction and efficiency improvement strategies of BC and HJT to the industrialization process of new metallization processes such as copper electroplating and silver-coated copper; from the continuous optimization model of the levelized cost of energy (LCOE) of large-scale ground power stations to emerging application scenarios such as space PV... With a cutting-edge perspective, industrial depth and global vision, the summit will present every participant with a technical and ideological feast that combines academic excellence and industry breadth.

Meanwhile, the summit will specially emphasize the core topic of "how to realize the transformation from laboratory to industrialization". In the current market environment where technologies are accelerating differentiation and capital is becoming more rational, a single technological breakthrough is no longer sufficient to build competitive barriers. How to realize the engineering verification of cutting-edge technologies, supply chain collaboration and business model innovation has become an important factor determining the success or failure of technical routes. The summit will build an in-depth docking platform for "industry-university-research-application", promote the precise matching between technology suppliers and industrial demanders, and accelerate the transformation of innovative achievements into real productive forces.

Every leap of the PV industry stems from the underlying drive of technological innovation. In 2026, a year of in-depth industry adjustment and fierce competition and cooperation among technical routes, the 2nd PV CTO Summit & Technological Innovation Conference is not only a high-density convergence of technical information, but also a "summit dialogue" that reshapes industrial cognition and builds strategic consensus.

From November 17 to 20, in Chengdu, China, the 9th China International Photovoltaic and Energy Storage Industry Conference 2026 looks forward to working with global PV technology leaders, industrial decision-makers and innovation practitioners to jointly explore the territory of technological innovation and jointly open the future of PV and energy storage. Here, you will meet the key forces that define the next five years.
