HJT Modules

Advantages of HJT Solar Modules

Backed by Dinto Solar’s advanced heterojunction expertise, our HJT modules deliver champion power output of up to 760 W with 24.47% efficiency. Enabled by an optimized microcrystalline silicon process and mature 0BB busbar-free technology, the modules achieve lower resistive losses, higher conversion efficiency, and long-term reliability. With high bifaciality, an excellent temperature coefficient, and superior low-light performance, they are well suited for utility-scale power plants as well as space-constrained commercial, industrial, and residential rooftops. Advanced encapsulation using butyl edge sealing and light-conversion films further enhances durability, bifacial energy gain, and degradation resistance, delivering higher lifetime energy yield.

Efficiency, Defined by Heterojunction

HJT technology combines crystalline silicon with ultra-thin amorphous silicon layers on both sides of the wafer. The intrinsic and doped a-Si layers form the critical heterojunction interface, effectively passivating the silicon surface, minimizing energy losses, and unlocking higher conversion efficiency. Dinto Solar has achieved a champion HJT cell efficiency of 26.9% and a module efficiency of 24.47%.

Lower Module Degradation

Thanks to n-type wafers and low-temperature fabrication, HJT modules effectively eliminate LID and PID. First-year degradation is below 1%, and over 30 years total degradation is ≤9.7%, ensuring stable long-term power output and reliable investment returns.

Higher Bifacial Energy Yield Gain

Dinto Solar’s HJT modules achieve a stable bifaciality of 90% ±5%. Both sides of the n-type silicon wafer are coated with identical intrinsic and doped a-Si layers and TCO films, enabling rear-side efficiency nearly equal to the front. Compared with TOPCon modules, HJT modules achieve approximately 2–5% higher bifacial energy yield.
