Theoretically, introducing an IB lets two photons with energy below the bandgap to excite an electron in the valence band into the conduction band. This enhances the induced photocurrent and thereby effectiveness.[121] ions that have absorbed this radiation can interact with each other as a result of an upconversion procedure. https://conkeysbakery50370.blogaritma.com/34712550/an-unbiased-view-of-mppt-solar-cell-charger
