HJT (Heterojunction with Intrinsic Thin Layer).
Heterojunction solar technology combines industry-leading efficiency with scalable manufacturing and long-term performance stability. With conversion efficiencies exceeding 30% in bifacial designs, excellent high-temperature behavior, and declining production costs, HJT represents a key driver for the next generation of high-performance solar systems.
Its ability to maximize energy output per square meter makes it especially attractive for space-constrained markets, large-scale utility projects, and regions with high solar irradiation—positioning HJT as a cornerstone technology for the future of clean energy.
Heterojunction (HJT) solar panels are one of the most advanced photovoltaic technologies available today. By combining high efficiency, superior temperature performance, and strong bifacial capability, HJT modules offer higher energy production and long-term reliability for a wide range of solar applications.
