From: A polymer scaffold for self-healing perovskite solar cells

Figure 3

(a) Schematic diagram of the energy offsets between CH3NH3PbI3 and PEG. (b) PL spectra of pristine perovskite film (control) and the corresponding perovskite film after being coated with PEG. (c) Characteristics of PL transient spectra of PEG scaffold perovskite films and perovskite film without PEG, indicating the similar lifetime of carriers in perovskite with and without PEG scaffold.
