Unraveling Bulk Degradation Mechanisms of Wide-Bandgap Perovskite Absorbers for Tandem Applications.

COChiara OngaroMOMostafa OthmanCBChristophe Ballif

Key Points

  • To investigate the degradation mechanisms of wide-bandgap perovskite absorbers in tandem solar cells.
  • Conducted experiments to analyze degradation under different operational conditions.
  • Utilized interface engineering techniques to improve stability.
  • Performed long-term stability assessments of absorbers.
  • Identified key degradation pathways affecting the longevity of absorbers.
  • Demonstrated improved stability through optimized interface engineering techniques.
  • Found that certain configurations significantly enhance performance over time.

Abstract

Wide-bandgap (WBG) perovskite absorbers play a pivotal role in enabling high-efficiency tandem solar cells; yet, their long-term operational stability remains a significant hurdle to commercialization. Although interface engineering has led...
