Co-firing process directly influences all three kinds of losses in solar cells; i.e., optical, recombination and resistive losses.

This is completely different in solar cells: In this case, the internal resistance is relatively high and depends greatly on the illuminance. In a 0.6V/150mV silicon solar cell, the internal resistance is up to 4 ohms in bright lighting. This is why the voltage drops significantly when a low-resistance load is connected.
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.
Perhaps the most development of the ultra-thin single crystal silicon solar cell. These 0.05 mm cells were tested radiation resistance (important for space applications), and a low weight. much lower cost. However, since efficiencies were already in the 10-13% range, the major efficiencies. silicon.
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.

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.
The series resistance, commonly represented as Rs, generally arises from both the inherent resistance of the semiconductor material forming the solar cell and the resistance of the semiconductor material at the interface with the metal contacts .
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.
