jeheron Posted May 4, 2007 Share Posted May 4, 2007 I have recently started studying the photoelectric effect. I currently have very little understanding of the theory. As i understand it retarding voltage is a voltage applied to the anode and the cathode of a photovoltaic cell such that any photoelectrons emitted are decelerated just enough such that they don’t reach the anode. This is a very superficial understanding, and could be totally wrong. Can anyone help me qualitatively refine my understanding? Also, why is a retarding voltage ever used? Jack.

Meir Achuz Posted May 4, 2007 Share Posted May 4, 2007 You are basicly correct. The retarding voltage V that stops any photo-electric current gives a measure of the maximum energy of the emitted electrons in eV. Link to comment Share on other sites More sharing options...
