Surface Treatment Reagent for Perovskite Solar Cells: DMPESI
Superior PCE and device stability are realized by surface treatment of perovskite layer with DMPESI.
Advantages
- Stronger bonding ability to perovskite surface than PEAI (= 2-Phenylethylamine Hydroiodide) 1)
- Suppresses phase transition of FAPbI3 from α phase to δ phase
- Improves device stability under high temperature and humidity or light soaking conditions by the suppression of ion migration and the influence of external atmosphere
- Low water content (<200 ppm)
Application
