From November 17 to 20, the 9th China International Photovoltaic and Energy Storage Industry Conference 2026 will be grandly held in Chengdu, China. During the conference, the 22nd China Solar Grade Silicon and Photovoltaic Power Generation Symposium (22nd CSPV) will be held concurrently. The 22nd CSPV will focus on the efficient leapfrog technology and scenario-based innovative applications of TOPCon, bringing together industry experts, leading enterprises, material suppliers, and power plant investors to jointly analyze cutting-edge technologies, gauge industry trends, and facilitate collaborative innovation throughout the industrial chain.

Under the guidance of the "dual carbon" goals, the photovoltaic (PV) industry has transitioned from a "scale-driven红利 period" to a "value-driven deepening period," with efficiency enhancement and scenario-based applications becoming the core drivers of high-quality industry development. TOPCon solar cells, with their high efficiency and good compatibility with large-scale manufacturing, have evolved into a mainstream technology accounting for 80% of the market share. Currently, although TOPCon technology has achieved significant breakthroughs, there is still a gap to reach its theoretical efficiency limit. Every 0.1% increase in efficiency requires overcoming multiple technical bottlenecks. Moreover, the accelerated construction of national wind and solar bases and the expansion of diverse "PV+" scenarios pose even higher demands on the performance and reliability of TOPCon modules. The 22nd CSPV will focus on the two core directions of efficiency enhancement and scenario-based innovative applications of TOPCon technology, building a communication platform that deeply integrates industry, academia, research, and application based on industrial realities and cutting-edge technologies to address industry development pain points.

Sharing and exchange at the 21st China Solar Grade Silicon and Photovoltaic Power Generation Symposium

In terms of technological leapfrogging, industrial-grade TOPCon cells face key pain points such as limited emitter passivation quality, high carrier transport losses, and interface degradation caused by back-side silver diffusion. Technical breakthroughs and material iterations have become the core avenues for efficiency enhancement and cost reduction. The symposium will invite industry technical experts, scholars from research institutions, and technical leaders from leading enterprises to conduct in-depth discussions on the cutting-edge aspects of TOPCon technology, interpret structural optimization strategies, explore innovative back-side technologies, exchange directions for core material iterations, and share process optimization paths. This will assist enterprises in breaking through technical bottlenecks, propelling the efficiency of TOPCon cells towards their theoretical limits, while reducing non-silicon costs and enhancing the industry's core competitiveness.

In terms of scenario-based innovative applications, 2026 marks the beginning of the 15th Five-Year Plan period, with the construction of large-scale wind and solar bases entering an accelerated phase. Over 85 GW of new energy base projects in China have made key progress, with重点项目 (key projects) such as "desert-gobi-barren land" bases and integrated water-wind-solar bases continuing to advance. Simultaneously, the continuous expansion of diverse "PV+" scenarios provides broad application spaces for TOPCon modules.

The 22nd CSPV will focus on the construction needs of national wind and solar bases, discussing optimization solutions for the reliability and weather resistance of TOPCon modules in special scenarios such as deserts and gobis, and adapting to the technical requirements for the协同发展 (collaborative development) of photovoltaic, wind, and energy storage. Focusing on diverse "PV+" scenarios, it will share innovative application cases of TOPCon modules in industrial, commercial, distributed, and residential sectors, analyze paths for technical adaptation, cost control, and revenue enhancement in scenario-based applications, and promote the continuous and deep integration of TOPCon technology with end-use scenarios, continuously unlocking industrial value.

The high-quality development of the PV industry relies on the collaborative efforts of the entire industrial chain, from upstream to downstream. The 22nd CSPV will fully leverage the platform advantages of the 9th China International Photovoltaic and Energy Storage Industry Conference 2026, building a comprehensive communication platform for module enterprises, wafer/cell enterprises, material suppliers, equipment manufacturers, research institutes, end-use applications, and industry experts to promote deep collaboration in technological innovation, material upgrades, equipment iterations, and scenario applications. Through sessions such as cutting-edge sharing, roundtable discussions, and supply-demand matching, it will focus on common industry issues, forge development consensus, promote resource integration throughout the industrial chain, and assist the PV industry in transitioning from scale expansion to quality and efficiency improvements.

Currently, TOPCon technology is at a critical stage of efficient leapfrogging, with scenario-based applications becoming a new engine for industry growth. From November 17 to 20, the 9th China International Photovoltaic and Energy Storage Industry Conference 2026 sincerely invites colleagues from all sectors of the industrial chain to gather in Chengdu for the 22nd CSPV. Here, you can share cutting-edge achievements, spark intellectual collisions, connect with high-quality resources, break through development bottlenecks through technological innovation, expand development spaces through scenario integration, and jointly promote the high-quality development of the PV industry, injecting even stronger PV momentum into the realization of the "dual carbon" goals.
