Bringing back-contact to the foreground

Solar manufacturers are pursuing the next-generation crystalline silicon (c-Si) PV cell technology. Back-contact (xBC) technologies including TOPCon back-contact (TBC), HJT back-contact (HBC), and HJT TOPCon back-contact (HTBC) have emerged as leading candidates, attracting attention for their superior conversion efficiency and aesthetic module designs. InfoLink analysts Derek Zhao and Kyle Lin examine xBC’s market potential.

As manufacturing processes mature and costs decline, xBC is emerging as one of the most promising technologies for industrialization, following tunnel oxide passivated contact (TOPCon) and heterojunction (HJT) technology.xBC has demonstrated notable advantages over other silicon PV technologies. Its structure eliminates front-side gridline shading, increasing the active cell area and resulting in significantly higher conversion …
