3.3 Intensity Modulation Current Transfer Function
At each modulating frequency, we measure AC output voltage across the load and AC light intensity incident upon the cell using a calibrated diode detector. To obtain a photocurrent needed in the transfer impedance calculation, we undertake the followings
(a) finding a conversion factor between the short circuit currents of the solar cell and the diode detector under the same incident light.
(b) assuming that the short circuit currents of the solar cell and the diode detector vary linearly with the incident light intensity.
(c) we compensate the effects of a finite
shunt resistance (6.40 Ω ) and non-zero
