Is the photoelectric effect in a photocell reversible?

[QUOTE="spareine, post: 5933050, member: 351563"] Is the photoelectric effect in a photocell reversible? Suppose both the cathode and the anode of a photocell are from cesium. The anode and the cathode are externally (outside the photocell) connected by a copper wire. Cesium has a threshold frequency of 470 THz. The cathode is illuminated with monochromatic light of frequency 570 THz. Electrons fly from the cathode to the anode without acceleration of deceleration because no voltage source is connected to the anode. Two questions: 1) Does the anode emit light? 2) If the anode emits light: is the frequency of that light monochromatic 470 THz, or is the frequency in a continuous range from 470 to 570 THz? [/QUOTE]
