Q: What is HJT module?
A: Heterojunction (HJT) is a special PN junction, which combines two different technologies into one cell: a crystalline silicon cell sandwiched between two layers of amorphous “thin-film” silicon. Compared with using any technology alone, these technologies can be used together to harvest more energy.
Q: What is n type Solar Cell?
A: An N-type solar cell consists of a thin p-type silicon (doped with boron) layer over a much thicker n-type silicon (doped with phosphorus) layer. Electrical contacts are applied to both sides. The p-side is the front side facing the sun.
