Since 2024, the global photovoltaic industry has experienced a situation of stark contrasts: on one hand, the demand for energy transition continues to grow, while on the other, rapid price declines triggered by phased overcapacity persist. However, according to calculations by relevant institutions, for China to achieve carbon neutrality between 2050 and 2060, solar energy needs to account for 23%. In 2024, its share was less than 3%. This implies a growth potential of 677% for solar energy, requiring an average annual addition of 500-700 GW of new PV installed capacity.

In the long run, effectively promoting the energy transition is the fundamental requirement. Internal competition is never the solution; innovation is the key to breaking through this cyclical industry downturn and the essential tool for the future prosperity of the PV industry. As a major participant in China"s PV industry, Tongwei Co., Ltd. has always regarded technological innovation as a key measure to resist risks and enhance its core competitiveness.

In March this year, Tongwei"s PV Technology Center announced that, following tests by the international authoritative certification body TÜV, the front-side power of Tongwei"s TNC 2.0 module reached 682.8 watts under the standard size of 2382*1134mm (approximately 60 watts higher than the current mainstream mass production power for the same module type on the market), with a conversion efficiency of 25.28%. Under the standard size of 2384*1303mm, the power of Tongwei"s TNC 2.0 module reached 778.5 watts (also about 60 watts higher than the current mainstream mass production power for the same module type), with a conversion efficiency of 25.06%, once again breaking the module efficiency and power records for two mainstream TOPCon module types.

As the global leader in both polysilicon and cell production, Tongwei has maintained its consistent steady operational pace. Facing a deep industry adjustment, Tongwei has chosen to counter price declines with technological revolution, building a unique breakthrough path through technological innovation. In 2024, Tongwei"s Global Innovation R&D Center officially became operational, focusing on numerous cutting-edge technologies in the PV field and continuously exploring deep and uncharted technological territories.

Over the past three years, Tongwei"s cumulative R&D investment has exceeded 11 billion yuan. To date, Tongwei has established the industry"s most advanced and comprehensive R&D platform, fully deploying R&D for mainstream industry technologies including TOPCon, HJT, xBC, and perovskite/crystalline silicon tandem cell and module technologies, conducting substantial technical reserves, and laying the foundation for development in the next 5-10 years.

Centered on TNC technology, Tongwei is deeply advancing efficiency improvements and cost reduction from multiple dimensions. Through measures such as optimizing production cycle times, upgrading screen patterns, recycling chemicals, and introducing localized pastes, it has set industry benchmarks in single-line capacity, Grade A rate, conversion efficiency, and non-silicon costs.

Supported by strong technical capabilities, the power of TNC and THC modules has repeatedly broken records. Tongwei has also planned a series of integrated cell and module efficiency enhancement solutions to further increase the mainstream power levels of mass-produced TNC modules, further highlighting the differentiated advantages in product power.

In 2025, Tongwei Group was once again listed on the Fortune Global 500, becoming the only global PV enterprise to be listed for three consecutive years. Simultaneously, Tongwei Solar successfully was selected into the World Economic Forum"s latest group of "Lighthouse Factories," becoming the first "Lighthouse Factory" in the global PV cell industry.

In the grand narrative of global energy transition, the PV industry once advanced rapidly, becoming a key force driving sustainable development.

Now at a node of change, under the stress test of cyclical industry adjustment, Tongwei Co., Ltd., with its technological moat and strategic resolve, has demonstrated the risk resilience and foresight of a leading enterprise.
