Overview

Randomized trial demonstrates improved efficiency in perovskite solar cells, suggesting enhanced performance through additive use.

Key Points

  • The primary aim is to investigate how a small molecule additive can regulate residual strain and enhance defect passivation in perovskite solar cells.
  • Utilized 1,2-diformylhydrazine as a precursor additive in perovskite formulation.
  • Evaluated the impact of the additive on residual strain and defect levels in inverted solar cells.
  • Measured efficiency and performance metrics of optimized solar cells.
  • Achieved significant improvement in maximum power conversion efficiency.
  • Demonstrated effective reduction in residual strain and defect density in the solar cells.
  • Results indicate that the additive plays a crucial role in enhancing solar cell performance.
