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 most common parasitic resistances are series resistance and shunt resistance. The inclusion of the series and shunt resistance on the solar cell model is shown in the figure below. Parasitic series and shunt resistances in a solar cell circuit.
Hence photovoltaic panels are usually rated in terms of their ‘peak’ watts (Wp). The fill factor (FF), is a measure of the junction quality and series resistance of a cell. It is defined as Obviously, the nearer the fill factor is to unity, the higher the quality of the cell.
Parasitic series and shunt resistances in a solar cell circuit. In most cases and for typical values of shunt and series resistance, the key impact of parasitic resistance is to reduce the fill factor. Both the magnitude and impact of series and shunt resistance depend on the geometry of the solar cell, at the operating point of the solar cell.
Since the value of resistance will depend on the area of the solar cell, when comparing the series resistance of solar cells which may have different areas, a common unit for resistance is in Ωcm 2. This area-normalized resistance results from replacing current with current density in Ohm's law as shown below:
The series resistance (r s) of a PV cell is low, typically <1Ω for cells designed for operation at 1 sun and <0.1Ω for concentrator cells. As a result, direct contact to the cell bus bar with specially designed 2-point probes is essential to obtain accurate forward bias I-V measurements.

Photoconductive Cell
When the photoconductive cell is exposed to external light, the resistance of the photoconductive cell decreases, resulting in a large current flow called the joint current. This is because the light energy supplied to the photoconductive cell causes its covalent bonds to be broken, resulting in the creation of electron-hole pairs.
