In the dark you always have one Fermi-level, because of the law of mass action that is all that is needed to get the correct electron and hole populations in the conduction and valence bands. When illuminated the Fermi-level can split and to get the correct number of electron and holes we need to use a quasi Fermi-level description. | |
