You can find the fill factor of a solar cell using an IV curve. Fill factor can be defined using the equation: Where P max is the maximum power output, J SC is the short circuit current density and V OC is the open circuit voltage. Fill factor is often referred to as a representation of the squareness of the IV curve.
Fill factor (FF) is an important measurement that you can use to evaluate the efficiency of solar cells. To calculate fill factor, you need to divide the maximum possible power output of a cell by its actual power output. This will give you a measurement that you can use to assess the performance of your solar cell.
Solar cell parameters gained from every I-V curve include the short circuit current, Isc, the open circuit voltage, Voc, the current Imax and voltage Vmax at the maximum power point Pmax, the fill factor (FF), and the power conversion efficiency of the cell, η [2–6].
Power curves can be used with J-V curves to determine P max, and therefore FF. Fill factor is determined by the series resistance (Rₛ) and shunt resistance (Rₛₕ) of a cell. Series resistance refers to the resistance of the cell’s internal components, while shunt resistance is resistance due to the external connections.
After completion of the solar cell manufacturing process the current–density versus voltage curves ( J ( U) curves) are measured to determine the solar cell's efficiency and the mechanisms limiting the efficiency. An accurate and robust analysis of the measured curves is essential.
