Theoretically, introducing an IB allows two photons with energy fewer than the bandgap to excite an electron within the valence band to the conduction band. This improves the induced photocurrent and therefore performance.[121] Skinny-film solar cells are a lot less preferred than traditional crystalline silicon choices for household and business https://dallaszvnds.slypage.com/37206258/the-fact-about-3000w-solar-cell-price-off-grid-that-no-one-is-suggesting
