Ion beam technology offers pathway to low-defect silicon solar cells

Researchers in India demonstrated that ion beam implantation enables precise boron doping in silicon solar cells, reducing defects and improving charge transport. The proposed approach could support more efficient and reproducible p-n junctions, offering a pathway to higher-performance silicon photovoltaics.Researchers at Panjab University in India have demonstrated a new method for doping silicon solar cells using ion beam technology, achieving improved electronic properties and reduced defect-related losses. "Defects in TOPCon and PERC solar cells often arise from conventional fabrication processes ...
