Photocurrent density formula
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… WebWe exploit continuity equation that governing charge carriers transport in semiconductor materials and use Newton's quadrature integration method over the entire solar spectrum ranging from 1 eV to 4 eV. For this calculation, we have found values of the short-circuit photocurrent density equal to 24.5 mA.cm-2, 19.3 mA.cm-2, 17.5 mAcm-2

WebElectrons will move toward the positive potential on the Cathode, and the holes will move toward the negative potential on the Anode. These moving charge carriers form the current (photocurrent) in the photodiode. Figure 1 shows the different layers of a photodiode (P-N Junction) as well as multiple connection points on top and bottom. Figure 1.
