Dinto Solar is driving a specialized strategy focused on Heterojunction (HJT) solar cell technology, advancing both its R&D and integrated manufacturing capabilities. Notably, the company is concentrating on next-generation perovskite-HJT tandem solar cell technology, setting an ambitious target of achieving over 30% cell efficiency. This pursuit of high efficiency is supported by a robust collaboration framework with value chain partners. Dinto Solar has significantly accelerated its commercial momentum, exemplified by its selection as a strong contender in large-scale procurement programs conducted by major Chinese power companies in 2026.
Technical & Product Details
Dinto Solar’s core HJT technology achieves high passivation effects and excellent carrier transport characteristics by depositing amorphous silicon thin films on a crystalline silicon substrate. Furthermore, the perovskite-HJT tandem cell, formed by layering a perovskite material on top of an HJT cell, combines two cells with different spectral absorption properties. This allows for broader utilization of solar energy that cannot be captured by a single cell. Consequently, it is expected to achieve power conversion efficiencies exceeding 30%, surpassing the theoretical limits of conventional silicon solar cells. This high efficiency is extremely advantageous for maximizing power generation in limited areas and relatively reducing installation costs.
Background & Industry Context
The global solar power market continues to grow, driving increased demand for higher efficiency and lower-cost technologies. HJT technology is garnering attention as one of the next-generation mainstream technologies, offering higher efficiency, a superior temperature coefficient, and bifacial power generation capabilities compared to the already established PERC (Passivated Emitter and Rear Cell) technology. Dinto Solar is leveraging the strengths of HJT while further advancing its tandem integration with perovskites to achieve technological differentiation. The large-scale procurement from Chinese power companies aligns with the government’s renewable energy promotion policies, serving as proof that Dinto Solar’s technology is receiving high evaluation and trust in the market. This is a classic example of technological innovation combining with national strategy to drive rapid commercialization.
Strategic Significance & Outlook
Dinto Solar’s pursuit of over 30% efficiency with HJT and perovskite-HJT tandem technology, coupled with its success in securing major contracts with leading Chinese power companies, strongly underpins its future potential. This commercial success will enable further investment in R&D and manufacturing capacity expansion, accelerating the mass production of high-efficiency tandem solar cells. In the global market, Dinto Solar’s technology will enhance its competitiveness as a sustainable energy solution and is expected to play an indispensable role in achieving renewable energy deployment targets. As cell efficiencies exceeding 30% are realized at the product level and long-term reliability is demonstrated, the company will further solidify its position as a key player in the solar PV industry.
