CCTV-10 Features Dinto Solar’s Work on HJT Products

A short documentary on CCTV-10, China Central Television’s science and education channel, examined how Dinto Solar is working to improve solar cell conversion efficiency. The feature highlighted the company’s in-house development of HJT cells and modules and its efforts to bring the technology into industrial production.

Dinto Solar holds 100 Chinese patents and is recognized as a national high-tech enterprise. Beyond module manufacturing, it is developing PV solutions tailored to industrial sites, buildings, transport infrastructure and rural communities.

Dinto Solar Wins Two Honors at the 2026 BJX PV Awards

Dinto Solar received two honors at the 15th BJX PV Awards in China: one for its influence as a PV cell brand and another for its work as an employer in smart PV manufacturing. The awards recognize both the company’s HJT technology and the people who bring it into production.

Dinto Solar Names JJ Energy Its Exclusive Partner in Thailand

Under a 2026–2027 agreement, JJ Energy Company Limited will serve as Dinto Solar’s exclusive partner in Thailand. The agreement calls for an initial supply of 30 MW of Dinto Solar’s flagship G12-132 HJT modules for commercial and industrial rooftop projects.

For Thai rooftop operators, heat and humidity pose different challenges. The G12-132’s superior temperature coefficient of −0.24%/°C helps limit power loss as module temperatures rise. Butyl edge sealing helps prevent moisture ingress, while coated glass on both sides contributes to the module’s weather resistance.

SolarQuarter Examines HJT’s Value Beyond Peak Efficiency

In its analysis of HJT, SolarQuarter looks beyond module efficiency to the electricity a solar plant can generate over 25 to 30 years. High bifaciality helps modules capture reflected light, while a superior temperature coefficient limits power loss as cells heat up. The article cites the 600 MW Gurbantunggut Desert project in Xinjiang, China, as an example of HJT deployment in demanding conditions.

On the manufacturing side, SolarQuarter identifies thinner wafers and reduced silver use as two ways producers are bringing down costs. It highlights Dinto Solar’s independent development of both silver- and copper-metallized HJT cells, as well as its module portfolio for utility-scale, offshore and vertical PV projects.

TOYO and SEG Solar Advance U.S. HJT Manufacturing in Texas

TOYO completed the expansion of its module facility in Humble, Texas, bringing annual module capacity to 2 GW. Its next planned investment at the site is a US$357 million, 1.5 GW HJT cell line, with pilot production targeted for the first quarter of 2028. Its longer-term U.S. plans call for 3 GW of HJT cell capacity and 6 GW of ingot and wafer capacity.

In nearby Tomball, SEG Solar produced the first SIERRA N series HJT module at its second U.S. manufacturing facility, which has a planned annual capacity of 4 GW. A third module facility, designed for 4.6 GW annually, is under construction and expected to begin operations in 2027. That would bring SEG’s total U.S. module capacity to 10.6 GW. In October, SEG also secured land in Tomball for a planned 4 GW HJT cell plant as it works toward an integrated U.S. supply chain.
