The solar cell delivers a constant current for any given illumination level while the voltage is determined largely by the load resistance. The short circuit photocurrent is obtained by integrating the product of the photon flux density and QE over photon energy.
The power can be extracted from the device in a region shown in the fourth quadrant. The solar cell is the basic building block of solar photovoltaics. When charged by the sun, this basic unit generates a dc photovoltage of 0.5 to 1.0V and, in short circuit, a photocurrent of some tens of mA/cm2.
The simplest equivalent circuit of a solar cell is a current source in parallel with a diode, shown in Fig. 2 . The series resistance R S represents the internal losses due to the current flow. Shunt resistance R sh, in parallel with diode, this corresponds to the leakage current to the ground.
If, for example, the global short circuit current is too low, that may indicate that it is just too low everywhere or that it might be allright on most parts of the cell but really lousy in some small areas. If you don't know what is the reason, you can't fix the problem. A perfect solar cell would show only one color - the optimal value.
