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.
Resistive effects in solar cells reduce the efficiency of the solar cell by dissipating power in the resistances. 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.
Series resistance does not affect the solar cell at open-circuit voltage since the overall current flow through the solar cell, and therefore through the series resistance is zero. However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance.
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.
How does the resistance theoretically behave for most commercially available photovoltaic modules, when an external DC voltage is applied to them, with and without illumination? It's common to wire solar panels of the same voltage in parallel, in order to provide greater current or greater resilience to partial shade.
The method for measuring the series resistance of a solar cell was first proposed by wolf and Rauschenbusch . This involves measuring the characteristic of a cell at two different illuminations.
