Crystallization dynamics control in perovskite films using alkylamines as additives in a 2-methoxyethanol-based antisolvent free process

SH Lee, S Hong, G Yoon, J woo Kim, HH Lee… - Materials Today …, 2024 - Elsevier
We found that the trace amount of alkylamine ligands added to perovskite solutions can act
as a nucleation promoter in an antisolvent-free process. We studied the effects of adding …

Benzodithiophene derivative 2D spacer as a defect passivation material in metal halide perovskite solar cells

S Hong, SH Lee, K Lee, JH Yum, JY Seo… - Journal of the Korean …, 2023 - Springer
Defect passivation is an efficient strategy for improving the performance of perovskite solar
cells (PSCs). In this study, we introduced a benzodithiophene-based 2D spacer with a short …
