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.
The value of R is determined (Swanson) using illuminated I–V characteristics at two close intensities. Agarwal et al. (1981) used the nonlinearity in the short-circuit current (I sc) at high intensity for the determination of the R s of the solar cell. Singh and Singh (1983) developed one-curve method to calculate Rs.
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.
