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
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.
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.
Shunt resistance (R s h) is created due to leakage currents produced at the edge of the f-PSCs and the imperfection of the cell structure . This affects the parallel conductivity of a solar cell depending on the cell junction [, , , ]. As leakage currents increase, the efficiency of any solar cell decreases.

Abstract The present study evaluates the sensibility of photovoltaics cells relative to changes in temperature.

Very high values of series resistance (Rs) and very low values of shunt resistance (Rsh) reduce short-circuit current density (Jsc) and open-circuit voltage (Voc), respectively. In this study, the analysis of Rs and Rsh for silicon solar cells using single and double exponential models are described.

Solar Cell. A solar cell is a device that uses sunlight to produce electricity. In the dark, its behaviour is identical to that of a diode. However, when illuminated, the I-V curve shifts downwards into quadrant IV. This makes a solar cell an active device, producing usable power. For this measurement, the Source Measure Unit is acting as a ...
