6 FAQs about [What does heterojunction battery efficiency mean ]

What is heterojunction technology?

Heterojunction Technology has been proven to increase efficiency, performance, and durability as a mature solar cell technology. Compared to other cell processing technologies, the production process of an HJT cell is more efficient and takes fewer steps.

What is a heterojunction solar cell?

Heterojunction solar cell technology is less affected by changes in temperature. This makes it great for applications in locations with high temperatures, which can negatively affect the performance of standard c-Si modules. HJT cell has a high bifaciality factor of 92%, making HJT deliver a great performance when designed as a bifacial module.

What is a heterojunction (HJT)?

A heterojunction (HJT) is a PN junction that combines two technologies into a single cell: a crystalline silicon cell sandwiched between two layers of amorphous “thin-film” silicon. These technologies can be used together to gather more energy than if they were utilized alone (HJT Solar|Based on N-type Silicon Wafer n.d.).
