Series resistance in a solar cell has three causes: firstly, the movement of current through the emitter and base of the solar cell; secondly, the contact resistance between the metal contact and the silicon; and finally the resistance of the top and rear metal contacts.
The characteristic resistance of a solar cell is the cell's output resistance at its maximum power point. If the resistance of the load is equal to the characteristic resistance of the solar cell, then the maximum power is transferred to the load, and the solar cell operates at its maximum power point.
The series resistance of a solar cell consists of several components as shown in the diagram below. Of these components, the emitter and top grid (consisting of the finger and bus bar resistance) dominate the overall series resistance and are therefore most heavily optimised in solar cell design.
Very high values of RS will also produce a significant reduction in ISC; in these regimes, series resistance dominates and the behavior of the solar cell resembles that of a resistor. The above equation is valid up to where the short circuit current is not affected by series resistance.
SHUNT RESISTANCE (Rsh) = Low shunt resistance causes power losses in solar cells by providing an alternate current path for the light-generated current. Such a diversion reduces the amount of current flowing through the solar cell junction and reduces the voltage from the solar cell.
Resistance is the opposition that a substance offers to the flow of electric current. There are various solar panel output parameters that can be measured and obtained during flash test, helping to judge on the performance quality of a solar panel.
