While in the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Electricity donors, are photoexcited to an enthusiastic state, they might transfer their Electricity non-radiatively to Bi2O2Se by means of dipole–dipole interactions. This causes electrons from the valence band of Bi2O2Se to transition to the conduction band.
