Limiting Defects in n‐Type Multicrystalline Silicon Solar Cells

Multicrystalline (mc) solar cells made from n‐type silicon feedstock have shown record efficiencies of 22.3% in a tunnel‐oxide passivating contact (TOPCon) cell structure. Still, material‐related carrier recombination limits the attainable efficiency. Herein, the findings of metallic impurity and st...
