Chapter 2: Spectral Response and Short Circuit current.

 

 

 
     
  Summary  
 
        This chapter describes the basic operation of a Solar Cell and uses a simplified analytical model which can be implemented in Pspice. Pspice models for the short circuit current, quantum efficiency and the spectral response are shown and used in several examples. An analytical model for the dark current of a solar cell is also described and used to compute an internel Pspice diode model parameter: the reverse saturation current which along with the model for the short circuit current is used to generate an ideal I(V) curve. Pspice DC sweep analysis is described and used for this purpose.
