The ideality factor of a diode is a measure of how closely the diode follows the ideal diode equation. The derivation of the simple diode equation uses certain assumptions about the cell.
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.
In the research production line at Fraunhofer ISE the three fill factors are usually recorded for every cell for characterisation purposes. Surprisingly, increased pseudo fill factors with values close to and above the value of FF 0 are found at times for single and multi crystalline silicon solar cells.
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.
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.
Therefore, the ideality factor is crucial in determining the electrical response and fill factor of solar cell devices [ 12, 13 ]. The value of ideality factor for conventional solar cells is typically between one and two; however, it can be greater than two for organic and perovskite solar cells.
Surprisingly, increased pseudo fill factors with values close to and above the value of FF 0 are found at times for single and multi crystalline silicon solar cells. These cells exhibit slightly up to strongly higher series resistance and pFF–FF difference than usual. Such a cell is presented in Table I as an example.
