High Efficiency Silicon Heterojunction Metal Wrap Through Produced in Industrial Pilot Line

In this work, we describe the development of metal wrap through (MWT) silicon heterojunction (SHJ) solar cells and modules using an industrial pilot line. We believe that MWT technology applied to SHJ cell can pave the way to a larger use of SHJ for single side PV module for residential and BIPV applications. The up to 5% power gain demonstrated is extremely important for the future of PV in such market segment and beyond and show once more the high potential of this technology.
