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

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

The company says THBC is different from conventional BC/TBC designs and aims to deliver higher efficiency and lower degradation.

The launch underscores continued industry interest in back-contact solar technology despite manufacturing and IP challenges.

It may shape which next-generation cell architectures gain traction against PERC, TOPCon, and HJT.
