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. Here, intensity of light means brightness. A bright light has more intensity ...

WebPhotocurrent linearity is determined by measuring the small change in photocurrent as a result of a small change in the incident light power as a function of total photocurrent or incident light power. Non-Linearity is the variation of the ratio of the change in photocurrent to the same change in light power, i.e. ∆I/∆P.

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.
