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 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.
Cell series resistance, R S = 2.0 Ω cm 2 The effect of series resistance on fill factor. The area of the solar cell is 1 cm 2 so that the units of resistance can be either ohm or ohm cm 2. The short circuit current (I SC) is unaffected b the series resistance until it is very large.
Series resistance (R s) mainly depends on the front and back surface contact resistance of f-PSCs [, , , ]. When increases R s then the carrier density decreases as a result current decreases in the cells.
The loss mechanism of the shunt path increases the leakage current which is higher than that of the ideal diode. This effect affects the J-V characteristics of the solar cells [, , , , , , ]. So, if the shunt resistance is reduced, the PSCs will be much more stable and get better efficiency at lower illumination.
