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 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), respectively.
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.
The resistive losses become larger as substrate size increases. However, in both (R sh) (Bowden and Rohatgi, 2001). In an n+–p or n+–p–p+ silicon solar cell, R is mainly the sum of contact resistance on the front and back surfaces and the ohmic resistances of the bulk and the n+ (and p+) diffused layers on the front (and back) sides.
While this is conceptually very simple there are often problems in practice. One of the biggest problems is that the cell series resistance is a lumped parameter composed of many resistances within the device.
