In the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, acting as Vitality donors, are photoexcited to an thrilled condition, they will transfer their Power non-radiatively to Bi2O2Se via dipole–dipole interactions. This causes electrons while in the valence band of Bi2O2Se to changeover for the conduction band. Within the PbS QDs/Bi2
