This study focuses on boron-doped p+polysilicon (poly-Si) passivating contacts using spin-on doping (SOD). Experimental conditions, including annealing conditions, SOD concentration, and poly-Si thickness, were controlled to improve passivation. Based on the analysis results, the passivation quality...
