Figure 8. (A) Intrinsic structure and PMs@MAPbI3 after CO2 adsorption partial density of states (PDOS). Black font represents CO2 orbital energy levels; green font represents LUMO orbital energy levels in PMs. (B) The electrostatic potential diagram of MAPbI3 and PMs@MAPbI3 adsorbed CO2. Red indicates positivity, while blue indicates negativity.
