Tianhe Solar's THBC Technology: A BC Battery Architecture That Defies Expectations

Tianhe Solar has unveiled THBC, a rear-contact solar cell architecture that moves all grid lines to the back of the cell.

The company says THBC differs from conventional BC and TBC designs and could deliver higher efficiency with lower degradation.

Tianhe Solar also argues the approach may ease manufacturing bottlenecks that have limited large-scale back-contact production.

The announcement adds to industry interest in back-contact technology as manufacturers weigh it against TOPCon, HJT, and PERC.
