Theoretically, introducing an IB makes it possible for two photons with energy below the bandgap to excite an electron in the valence band to the conduction band. This improves the induced photocurrent and thereby effectiveness.[121] Thin-movie solar cells are fewer well known than regular crystalline silicon selections for household and https://kob-khet-design93603.fitnell.com/77361110/5-easy-facts-about-advantages-of-solar-cells-described
