Key Solar Cell Parameters and Measurement Techniques
Typical forward biased I-V characteristic of a solar cell. (This feature is available on Model 4200 SCS with CV option)
Doping Density (N) of a Crystalline-Si solar cell can be derived from capacitance voltage sweep.

   
Shunt resistance of a solar cell can be estimated from reverse bias I-V sweep.
Series resistance (Rs) can be determined from forward I-V sweep of a solar cell at multiple light intensities.
