Inverted perovskite solar cells with self-assembled monolayer treated HTLs show improved efficiency and stability, achieving 24.38% by utilizing molecules like 2-mercaptoimidazole and 2-Mercaptobenzimidazole as additives for better electron transport layer quality and defect minimization.
- Cell design: Inverted perovskite solar cell with a self-assembled monolayer (SAM) treated HTL.
- Enhanced efficiency: Recorded at 24.38%, surpassing other designs and retaining over 89% of initial efficiency after 450 hours.
- Molecule additives: Use of molecules like 2-mercaptoimidazole (2-MeI) and 2-Mercaptobenzimidazole for better quality electron transport layer.
- Stability improvement: Increased stability against external/internal attacks due to the higher quality perovskite film.
- Journal publication: Details published in Cell Reports Physical Science, showcasing novel cell concept and technology advancements.
