Recently, the inaugural Solar Manufacturing USA 2026, jointly organized by pv magazine USA and Terawatt PV Research, was held in Austin, Texas, USA. Dr. Xing Guoqiang, Chief Technology Officer of Tongwei’s Photovoltaic Business, and Fan Hua, Vice President of Global Supply Chain, along with other Tongwei representatives, were invited to attend the event.

On the first day of the main conference, Dr. Xing Guoqiang delivered a keynote speech. From a global industry perspective, he provided a systematic analysis of the evolution of photovoltaic technologies, diverse advanced technology pathways, and Tongwei’s latest R&D and innovation achievements. His presentation resonated widely with industry experts from China and overseas and received a strong response from the audience.

1. Focusing on Industry Development, Tongwei Provides an In-Depth Analysis of Photovoltaic Technology Evolution

The summit focused on North American and global photovoltaic manufacturing capacity, the evolution of technology pathways, and collaborative development across the global supply chain. In his speech titled “PV Technology Evolution – Tongwei’s Perspective,” Dr. Xing Guoqiang reviewed the decades-long development of the global photovoltaic industry. According to the ITRPV photovoltaic learning curve, from 2006 to 2025, every doubling of cumulative global installed capacity was accompanied by a 40.8% decline in unit costs. Data from authoritative research institutions and publicly available market information show that photovoltaic module prices fell from approximately USD 1.20/Wp in 2011 to approximately USD 0.09/Wp in 2026.

Over the past two decades, photovoltaic technology has undergone rapid and continuous evolution, progressing from aluminum back-surface field (Al-BSF) technology to the P-type era dominated by PERC, and then to the N-type era featuring the rapid development of TOPCon, HJT, and BC technologies. Technological innovation and declining manufacturing costs have driven continued growth in global photovoltaic installations, contributing to the significant development of the industry. Since its commercialization in 2021, N-type TOPCon has rapidly expanded its market share, reaching 84% in 2025, and is expected to remain mainstream over the next five years.

2. Addressing Industry Challenges with Leading TNC, THC, and TBC Technology Pathways

As a leader in TOPCon technology, Tongwei has adopted a self-developed tubular PECVD technology pathway. Related achievements have been selected twice for the cover of *Progress in Photovoltaics*. PECVD technology accounts for approximately 57% of the TOPCon market and has received widespread recognition from the global photovoltaic academic and industrial communities.

Tongwei’s TNC cell and module products deliver industry-leading performance. Its three generations of products—TNC 1.0, featuring high cost-effectiveness; TNC 2.0, offering stable and high efficiency; and TNC 3.0, representing flagship innovation—cover a power range from 465 W to 770 W, comprehensively meeting the needs of utility-scale power plants, commercial and industrial applications, and residential scenarios.

Tongwei began investing in HJT technology R&D in 2018 and has continued to tackle core technologies, achieving key breakthroughs. In June 2026, Tongwei’s THC module achieved a power output of 802.43 W and a conversion efficiency of 25.83%, setting a new HJT module power record for the 12th time and reaching another industry milestone.

In terms of advanced technology development, Tongwei has established a multi-pronged technology portfolio and continued to build technological capabilities for future applications. Its xBC technology covers the range from p-TBC to n-HTBC, with R&D achievements ranking among the industry's leading levels. In 2025, Tongwei completed the industry’s first 5 MW perovskite tandem pilot line, continuing to explore future technologies and building a multi-dimensional technological innovation advantage.

3.Vertical Integration + Green Intelligent Manufacturing: Safeguarding the Global Supply Chain

At the summit, led by Dr. Xing Guoqiang and Vice President Fan Hua, Tongwei conducted comprehensive and in-depth technical and business exchanges with leading photovoltaic owners, developers, manufacturers, research institutions, and third-party testing and certification organizations from North America and around the world. Guests from across the industry spoke highly of Tongwei’s globally leading manufacturing capabilities and innovative achievements in cutting-edge technology R&D. A number of industry leaders noted that Tongwei’s continued investment in technology R&D and its pragmatic efforts to advance sustainable development across the industrial chain are providing sustained momentum for the high-quality development of the global photovoltaic industry.

Leveraging the advantages of a vertically integrated, full-chain industrial structure, Tongwei has established a complete industry footprint covering silicon materials, silicon wafers, solar cells, and modules. Its market shares in high-purity polysilicon and solar cells have ranked first globally for many consecutive years.

Tongwei Solar’s Meishan facility was selected as a World Economic Forum “Lighthouse Factory,” becoming the first “Lighthouse Factory” in the global photovoltaic cell industry. The company implements a 3S sustainability management system, with 100% of its core products covered by carbon footprint certification, providing efficient, reliable, and green solutions for customers worldwide.

Tongwei will continue to deepen cooperation with international industry partners, leveraging its leading mass-production technologies and advanced technology pipeline to support the high-quality development of the global photovoltaic industry, accelerate the global energy transition, and promote the arrival of the era of grid parity for solar and energy storage.
