In the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Electrical power donors, are photoexcited to an psyched condition, they're able to transfer their Power non-radiatively to Bi2O2Se via dipole–dipole interactions. This causes electrons from the valence band of Bi2O2Se to changeover on the conduction band. In the PbS
