Overview

Study reveals additional light anneal increases series resistance in polysilicon solar cells, suggesting optimized fabrication is crucial.

Key Points

  • Series resistance increased significantly, affecting overall solar cell performance despite enhanced light annealing.
  • Primary measure indicates an increase in open-circuit voltage and power conversion efficiency due to light anneal techniques.
  • Analysis included electrical measurements and luminescence imaging to investigate resistance at metal/silicon interfaces.
  • Findings underscore the importance of process sequence in achieving high-efficiency TOPCon solar cell fabrication.
