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

PKPiyumi Kanchana KodithuwakkuCSChristian SamundsettDMDaniel MacDonald

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.

Abstract

ZnO-based electron-selective passivating contacts, with a structure analogous to conventional polysilicon passivating contacts, but offering better optical transparency, have recently emerged as a promising technology for silicon solar cell applications....
