New Paper! Perovskite interface studies using photo-KPFM

posted Feb 16, 2018, 9:02 AM by Larry Renna   [ updated Feb 16, 2018, 9:03 AM ]

We show, using photo-KPFM, the macroscopic polarization effects of perovskite-charge transport material interfaces under illumination. See our latest publication in Materials Letters here: (Link).

Interface engineering to control ionic transport at perovskite interfaces

posted Aug 14, 2017, 8:10 AM by Larry Renna

Our paper in Adv. Energy Mater. is out! We use phenylene vinylene polymers containing cationic, zwitterionic, or anionic pendant groups to control ionic transport in perovskite devices. We extend this concept to make perovskite-based memristors. (Link)
