Is the photoelectric effect in a photocell reversible?

[QUOTE="spareine, post: 5933349, member: 351563"] LEDs are sometimes viewed as a sort of reverse photoelectric effect, where a current produces light. When an electron travels across the junction, its excess energy is released as a photon. The threshold voltage of the diode corresponds to the energy of the emitted photon. What is the difference between the junction of the diode and the anode of the photocell? [/QUOTE]
