Heterojunction solar cells have additional steps in the manufacturing process, but this does not highly increase the cost. Ultra-clean production and deposition steps demand specialized tools, notably a PECVD tool for amorphous silicon layers that can exceed $4 million per unit—nearly double the price of PERC coating. . Loom Solar has launched its latest innovation, the SHARK 730~750 W HJT Dual-Glass Solar Panel, featuring cutting-edge Heterojunction Technology (HJT) for superior performance. More than 25% cell efficiencies and 24% of solar panels.
