46% Efficient Organic Solar Cells with Concurrent Voltage Enhancement and Thermal Stability Enabled by Crystallization-Kinetics-Controlled Morphology

ALAnhai LiangCLChunliang LiBZBosen Zou

Key Points

  • This study aims to address the limitations of morphological instability and phase separation in organic solar cells.
  • Analyzed crystallization kinetics of non-fullerene acceptors.
  • Examined the effects of morphology on voltage and thermal stability.
  • Conducted efficiency assessments of the solar cells under varying conditions.
  • Achieved 20.46% efficiency in organic solar cells.
  • Demonstrated concurrent improvement in voltage and thermal stability.
  • Identified optimal morphology as a key factor for performance enhancement.

Abstract

Organic solar cells are often limited by morphological instability and suboptimal phase separation, largely stemming from the rapid crystallization kinetics of state-of-the-art non-fullerene acceptors, which lead to excessive aggregation and...
