On September 9, at the 2026 Private Economy Innovation and Development Conference, the All-China Federation of Industry and Commerce (ACFIC) released two major lists: the "2026 Top 500 Private Enterprises by R&D Investment" and the "2026 Top 500 Private Enterprises by Invention Patents". With sustained R&D investment and strong scientific and technological innovation capabilities, Tongwei has been successfully listed on both the "Top 500 by R&D Investment" and "Top 500 by Invention Patents" lists.

The two lists released by the ACFIC this time take corporate R&D expenditure and valid invention patents as their core evaluation indicators respectively. They comprehensively showcase the innovation input and intellectual property reserve of domestic private enterprises, and are regarded as a vane for observing the innovation vitality of China's private sector. According to the lists, the entry threshold for the "2026 Top 500 Private Enterprises by R&D Investment" is ‌481 million yuan‌ in R&D expenses, an increase of ‌16 million yuan‌ over the previous year.

The entry threshold for the "2026 Top 500 Private Enterprises by Invention Patents" is ‌216 valid domestic invention patents‌, an increase of ‌29‌ compared to the previous year. Tongwei's dual listing on both lists fully demonstrates its robust strength in deepening technological innovation and accelerating the cultivation of new quality productive forces.

Technological innovation is one of Tongwei's core competitiveness. In 2025, Tongwei's photovoltaic segment invested over ‌2.2 billion yuan‌ in R&D, accounting for ‌3.75%‌ of the photovoltaic business's operating revenue. This high-intensity R&D investment firmly places the company in the industry's leading tier. In recent years, Tongwei's photovoltaic segment has accumulated a total R&D investment of over ‌11 billion yuan‌. As of August 31, 2026, the total number of authorized patents in the photovoltaic segment has reached ‌4,413‌.

The implementation of these hard-core innovation achievements relies on the strong empowerment of top-tier R&D platforms. In June 2024, the Tongwei Global Innovation R&D Center was officially completed and put into operation. Positioned as the core technological driving force for the company's long-term development, it will continue to help Tongwei accurately anchor technological directions, prevent industrial risks, tap market opportunities, and iterate mainstream technologies over the next five, ten, or even longer years. At the same time, it will lead the innovation of cutting-edge photovoltaic technologies, foster new quality productive forces in the photovoltaic industry, and become a critical engine for technological breakthroughs across the entire sector.

In December 2025, through a rigorous selection process with an admission rate of only ‌8.5‰‌, Tongwei stood out and was approved as one of China's first batch of "National-level Manufacturing Pilot Platforms" — the only one in the photovoltaic industry. Leveraging this national-level platform and the company's own national-level technology center, Tongwei is comprehensively advancing parallel R&D and pilot verification of multiple cutting-edge technical routes, including TOPCon, HJT, BC, and perovskite/crystalline silicon tandem, accelerating the transformation of laboratory technologies into industrialized achievements. With its profound technological accumulation and scientific research strength, Tongwei has become a principal responsible unit for China's "15th Five-Year Plan" key R&D programs, contributing to the development of China's photovoltaic industry with high-standard R&D and innovation.

Advanced Photovoltaic Device Pilot Platform

From R&D investment to the accumulation of invention patents, from laboratory records to mass production breakthroughs, Tongwei has continuously translated its technological momentum into industrial competitive advantages. This listing is a full recognition of Tongwei's innovation practices. Moving forward, Tongwei will continue to focus on tackling core cutting-edge photovoltaic technologies, continuously increase R&D investment, deepen the integration of the innovation chain and industrial chain, give full play to its role as an innovation entity among private enterprises, and make greater contributions to the high-quality development of China's new energy industry and the advancement of global carbon neutrality.
