研究目的
Investigating the uniform arrangement of different-n-value 2D nanoplates in quasi-2D perovskites using vacuum poling for efficient, high-fill-factor solar cells.
研究成果
Uniform dispersion of different-n-value nanoplates via vacuum poling treatment leads to efficient isotropic carrier transport, achieving a record-high fill factor of 82.4% and power conversion efficiency of 18.04% in quasi-2D perovskite solar cells, along with superior stability.
研究不足
The study focuses on quasi-2D perovskites with specific compositions and may not be directly applicable to other perovskite systems. The vacuum poling method requires precise control over processing conditions.
