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 busbar resistance) dominate the overall series resistance and are therefore most heavily optimized in solar cell design.
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.
However, near the open-circuit voltage, the IV curve is strongly affected by the series resistance. A straight-forward method of estimating the series resistance from a solar cell is to find the slope of the IV curve at the open-circuit voltage point.
Series and shunt resistances in solar cells affect the illuminated current–voltage (I–V) characteristics and performance of cells. The curve factors of commercial solar cells are lower than ideal, primarily due to R (Wolf and Rauschenbach, 1963). The resistive losses become larger as substrate size increases. However, in both
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.
Parasitic series and shunt resistances in a solar cell circuit. The major contributors to the series resistance (Rs) are the bulk resistance of the semiconductor material, the metallic contacts and interconnections, carrier transport through the top diffused layer, and contact resistance between the metallic contacts and the semiconductor.

Series and shunt resistances in solar cells are parasitic parameters, which affect the illuminated current–voltage (I–V) characteristics and effi ciency of cells. Very high values of series resistance (R s) and very low values of shunt resistance (R sh) reduce short-circuit current density (J sc) and open-circuit voltage (V oc ...

Solar Module Cell: The solar cell is a two-terminal device. One is positive (anode) and the other is negative (cathode). A solar cell arrangement is known as solar module or solar panel where solar panel arrangement is known as photovoltaic array. It is important to note that with the increase in series and parallel connection of modules the power of the modules also gets added.
