Heterojunction Solutions

PV manufacturers are competing against each other in a constant race to increase cell efficiency. This challenge is driving the transition from mainstream passivated emitter rear contact (PERC) cells to Heterojunction (HJ) cells.

HJ solar cells pose specific challenges to equipment manufacturers in printing parameters, thin wafers handling and thermal process window.

Applied Materials offers a dedicated version of the Tempo Presto metallization line designed explicitly for HJ cells with multiple solutions for drying ovens and two alternative designs for curing ovens. Our systems, process development and integration, know-how combine to simplify the transition to higher efficiency, advanced cell architectures for the final customers.
