Web23 de jul. de 2010 · If an electron in a crystal gets hit by a photon that has enough energy, it can get excited enough to jump from the valence band to the conduction band, where it is free to form part of an electric current. That’s what happens when light strikes a solar cell, producing a flow of electrons. WebWe call the first energy level after the ground state the first excited state. Once the electron's at the higher energy level, it won't stay there long. Electrons, if given the chance, will fall towards the lowest energy level they can. So our electron will fall back down to the ground state and give up four eV of energy. gram smith orthogonalization processWeb14 de nov. de 2014 · When an electron temporarily occupies an energy state greater than its ground state, it is in an excited state.
