INNOVATING HETEROJUNCTION
SOLAR TECHNOLOGY
Dinto Solar consistently positions itself at the forefront of photovoltaic technology, bringing together leading talent in the field of heterojunction (HJT) innovation. The company has established a highly capable R&D team led by recognized industry authorities, making it one of the very few teams in China with long-term, dedicated engagement in heterojunction cell technology development. The team includes national-level high-end overseas talent, who also serves as the Chief Expert in photovoltaics for State Power Investment Corporation, while core members each possess more than 15 years of experience across the photovoltaic and semiconductor industries.
Dinto Solar maintains sustained and strategic investment in research and development. In recent years, the company has undertaken nearly ten municipal-, provincial-, and ministerial-level (or above) science and technology projects, while actively promoting deep integration between industry, academia, and research to rapidly adapt to evolving market demands. To date, Dinto Solar has applied for and been granted more than 100 high-quality invention patents, holds over 30 proprietary technical know-how items, and has multiple patented technologies recognized as internationally leading. As China’s first company with fully independent production capability for copper-metallized heterojunction (C-HJT) modules, Dinto Solar continues to explore effective solutions to further enhance solar cell efficiency, delivering superior and sustainable value returns to customers.
