(a) A photon with energy () greater than band gap energy () strikes on solar cell and excites an electron to Conduction Band (CB) from Valence Band (VB); (b) the extra energy () is released as phonon; (c) a photon with energy () greater than band gap energy () strikes on solar cell and excites an electron to CB from VB; (d) the extra energy () is used to produce higher voltage by (e) a photon with energy () more than band gap energy () strikes on solar cell and excites an electron; (f) extra energy () is used to excites one more electron from VB to CB.
