What Are HJT Solar Panels?

Heterojunction (HJT) solar panels—also known as Silicon Heterojunction (SHJ) or HIT (Heterojunction with Intrinsic Thin-layer) panels—represent a cutting-edge fusion of crystalline and thin-film solar technologies. Built on an N-type monocrystalline silicon base, these solar cells are layered with intrinsic and doped amorphous silicon, resulting in ultra-high efficiency, durability, and superior bifacial performance.
