The Effect of Intrinsic Defects in Grain Boundaries on Non-Radiative Recombination in CsPbI3 and CsPbBr3

LKLotte KortsteeNVNoam VeberBSBetty Shamaev

Key Points

  • This research investigates how intrinsic defects at grain boundaries affect non-radiative recombination in halide perovskites.
  • Conducted spatially resolved photoluminescence measurements around grain boundaries in CsPbI3 and CsPbBr3 materials.
  • Analyzed variations in emission intensity related to the presence of intrinsic defects.
  • Observed significant variations in photoluminescence intensity near grain boundaries, indicating strong influence of defects.
  • Identified a correlation between defect density and levels of non-radiative recombination, highlighting implications for device efficiency.

Abstract

The photoluminescence (PL) response of halide perovskite (HP) photovoltaic absorbers near grain boundaries (GBs) remains poorly understood. Spatially resolved PL measurements reveal pronounced variations in emission intensity around GBs, underscoring...
