During the PbS QDs/Bi2O2Se hybrid photodetector, when PbS quantum dots, performing as Electricity donors, are photoexcited to an fired up state, they can transfer their Electricity non-radiatively to Bi2O2Se by way of dipole–dipole interactions. This leads to electrons during the valence band of Bi2O2Se to transition to the conduction band. https://socialskates.com/story18567229/the-fact-about-%E0%B9%84%E0%B8%A7%E0%B8%88%E0%B8%A3-%E0%B8%87-that-no-one-is-suggesting
