Aiko Solar was the first to release ABC technology in 2021 and was the first in the industry to achieve GW-level mass production of N-type BC . The ABC product series covers various application scenarios including distributed generation, ground-mounted power plants, and floating power plants. With its advantages of high power, high safety, aesthetic appeal, and high intelligence , its market recognition and influence have rapidly increased.

In his address, Liu Yiyang, Executive Secretary-General of the China Photovoltaic Industry Association, stated: "Innovation is an eternal theme in industrial development and a crucial guarantee for the healthy and orderly development of the photovoltaic industry. Innovation, represented by BC technology, aligns with the national strategic direction of developing new productive forces. On the key path of breaking through homogenization, we have witnessed Aiko ABC technology achieving leadership in mass production efficiency and yield, and through breakthroughs in underlying processes such as silver-free metallization, achieving a balanced development of cost and performance for platform-based technologies."

In his address, Radovan Kopecek, founder and committee member of ISC Konstanz, envisioned a bright future for BC technology: "BC technology is rapidly gaining market share and customer recognition. With its future integration with energy storage, BC technology will demonstrate even stronger competitiveness. Currently, the mass production efficiency of BC modules can already reach 25%. We believe that the photovoltaic industry will undergo a major transformation in 2026 due to the continued improvement in the efficiency of BC modules, and BC modules are expected to gradually begin to dominate the market in 2027 and 2028."

Chen Gang, Chairman of Aiko Solar, delivered a keynote speech entitled "Leading Human Society into the Zero-Carbon Era," elaborating on the profound significance of photovoltaic technology revolution for the development of human civilization. The development of energy utilization methods and energy infrastructure provides support for socio-economic development and is a driving force for human progress. Photovoltaics is the most efficient form of solar energy utilization to date, enabling human society to break free from dependence on fossil fuels and move towards a new era of zero-carbon, sustainable development.

"After years of development, the photovoltaic industry has shifted from an era dominated by supply-side raw material shortages to an era dominated by grid parity. With the deepening of the new electricity reform and the full entry of new energy power generation into the market, customers need high-quality products that are scenario-specific and differentiated. The era of value competition dominated by demand has arrived," said Chen Gang. "Efficiency is the 'first principle' of the photovoltaic industry. Only by committing to technological innovation, continuously improving photoelectric conversion efficiency, meeting the differentiated needs of the market with high-quality products, and providing differentiated value to customers can photovoltaic companies truly weather the cycles and achieve high-quality development for the entire industry. Today, we are increasing the mass production efficiency of photovoltaic modules to 25%, and in 2026 we will increase it to 26%. In the next 14 years, we aim to reach a mass production efficiency of 35%. This process requires the joint efforts of all our colleagues in the BC ecosystem."

During the roundtable discussion themed "BC Technology: The Future is Here, and the Time is Right," Wang Yongqian, Chief Scientist of Aiko Solar, Tong Hongbo , Dean of the First Institute of LONGi Green Energy Central Research Institute , Peter Fath , CEO of RCT Solutions , and Gianluca Coletti, Chief Technology Officer of FuturaSun Group, participated in the discussion and shared their views on the advantages and future development path of BC technology . Ge Min, co-founder of TaiyangNews, moderated the roundtable discussion.

Industry collaboration to build a BC ecosystem

The disruptive innovation of BC technology compared to traditional technologies requires collaborative innovation across the entire industry chain to improve manufacturing levels and gradually form a healthy and virtuous cycle of development. This summit brought together companies and institutions from around the world involved in silicon material and wafer technology, cell and module R&D and production, testing and simulation, photovoltaic systems, and other related industries to jointly discuss the future technological development of the photovoltaic industry.

Technical representatives from numerous photovoltaic companies and research institutions , including Aiko Solar, LONGi Green Energy, GCL System Integration Technology, DIL Laser, Gogen Solar, Laplace New Energy, University of New South Wales (Australia), Delft University of Technology (Netherlands) , and TÜV Rheinland , along with authoritative technical experts such as Shen Hui, Director of the Yangtze River Delta Solar Photovoltaic Technology Innovation Center, and Shen Wenzhong, Director of the Solar Energy Research Institute of Shanghai Jiao Tong University , delivered a total of 30 keynote speeches, providing a systematic and comprehensive in-depth analysis of BC technology across the entire chain of design, production, testing, and application.

Furthermore, at the banquet on the first day of the summit, TÜV Rheinland awarded "Module-Level Fire Risk Resistance" certification to Aiko Solar and LONGi. In recent years, with the increasing scale of photovoltaic power plants, fire accidents have occurred frequently, posing a threat to the lives and property of users. To address this, TÜV Rheinland designed module-level fire risk resistance certification standards and testing specifications tailored to the needs of practical application scenarios. Test results show that BC modules have lower surface temperatures under high temperature and shading conditions, possessing unique advantages in fire resistance performance and better ensuring the safe operation of power plants.

Step into Yiwu and feel the pulse of "intelligent manufacturing".

During the summit , attendees also visited Aiko's Yiwu factory, experiencing firsthand the intelligent ABC battery and module production process. Currently, Aiko's ABC module delivery efficiency has ranked first in TaiyangNews' global module mass production efficiency ranking for 33 consecutive months . Full-screen ABC modules have also begun delivery to domestic and international markets this year, with a mass production delivery efficiency exceeding 25%, creating incremental value for market customers with leading technology.

As Chen Gang stated in his summit address, in this era of value competition, customer needs have become the core of photovoltaic companies' market expansion. Providing products and services that meet the differentiated needs of different customers is the only way for photovoltaic companies to seek a new round of growth. Aiko's high-efficiency ABC modules offer higher power generation in the same area, coupled with features such as optimized shading power generation, superior temperature coefficient, lower degradation, high-temperature suppression, and resistance to microcracks, addressing differentiated needs in different scenarios and maximizing customer value.
