Weekend Read: Connecting HJT

The application of busbarless cell interconnection approaches could unlock the potential of heterojunction (HJT) technology, primarily by reducing the historically high silver usage of negatively-doped, “n-type” cell technology. As HJT manufacturing increases, a wave of applications may very well be on the horizon.

Huasun announces world’s first 210R HJT modules based on rectangular cells

The company says its new 210R module series, such as the 630 W module for example, will reduce LCOE by 2.6% and increase project IRR by 3.9%. The Everest line of modules will be produced at Huasun’s three main bases with a total capacity of 12 GW.
