To understand the electronic behavior of a solar cell, it is useful to create a model which is electrically equivalent, and is based on discrete ideal electrical components whose behavior is well defined. An ideal solar cell may be modelled by a current source in parallel with a diode; in practice no solar cell is ideal, so a shunt resistance and a series resistance component are added to th… WebPhotocharge Generation Rate in Silicon Assume a monochromatic photon ux F0 photons/cm2.sec at wavelength incident at the surface (i.e., x= 0) of silicon PSfrag …
