Influence of Al doping ratio on properties of ZnO:Al passivating contacts for crystalline silicon solar cells

Key Points

• To investigate how different ratios of aluminum (Al) doping influence the properties of ZnO:Al electron-selective contacts for crystalline silicon solar cells.
• Evaluation of ZnO:Al structures with varying Al doping ratios.
• Comparison of optical and electrical properties across different doping levels.
• Assessment of contact performance in solar cell applications.
• Higher Al doping improves optical transparency of ZnO contacts.
• Optimized Al doping ratios enhance electron selectivity.
• ZnO:Al contacts show potential for better performance in solar cells than traditional polysilicon contacts.
