Metallization Pastes for n-Type Cells

Metallization Pastes for n-Type Cells

The share of n-type silicon solar cells is expected to increase in the coming years as wafer costs go down and the inherent higher quality silicon allows to achieve higher overall conversion efficiencies than p-type wafers. Due to the absence of Boron-Oxygen pairs, there is no light induced degradation in n-type cells.

The 3 major n-type cell architectures are:

  • n-PERT
  • Heterojunction
  • IBC

Heraeus is renowned for pioneering in metallization pastes for n-type solar cells. See here our metallization paste portfolio for this application.
