The Photoelectric Effect - Photocurrent versus Light …

WebThe generated photocurrent flows through Rdcausing a voltage across the diode. This voltage opposes the band gap potential of the photodiode junction, forward biasing it. The value of Rddrops exponentially as the illumination increases. Thus the photo-generated voltage is a logarithmic function of incident light intensity. WebNov 22, 2024 · But it makes sense that the green graph has a lower stopping voltage so hence it should be under the graph on the left, but then again that doesn't make sense to … WebA graph is drawn between light intensity along x-axis and the photocurrent along y-axis. From the graph in Figure 7.9, it is evident that photocurrent – the number of electrons emitted per second – is directly proportional to the intensity of the incident light.
