The Fill Factor is essentially a measure of the efficiency of a PV module, the theoretical maximum value depending on factors such as the type of silicon used to construct the module. However, deviation from the expected value or changes in Fill Factor can provide an indication that a fault is present.
What is solar fill factor?
The Fill Factor (FF) is essentially a measure of quality of the solar cell. It is calculated by comparing the maximum power to the theoretical power that would be output at both the open circuit voltage and short circuit current together.
Why is fill factor important?
The fill factor (FF) is an important parameter that determines the power conversion efficiency of an organic solar cell. There are several factors that can significantly influence FF, and these factors interact with each other very intricately. Due to this reason, a deep understanding of FF is quite difficult.
What affects the fill factor?
Fill factor in solar cells is affected by resistive parameters in a such devices: front and rear metallic contacts resistivities, bulk ressitivity, n+ and p+ emmiters resistivities and metal-emitters interfaces resistivities. In your case, it is clear that the degradation is due to the bulk (active layer) resistivity.
Can fill factor be more than 1?
Even if the series resistance RS= zero and the Shunt Resistance Rsh is infinity, the fill factor will be still less than one because of the recombination of the photo generated electron hole pairs in the solar cell diode. … As n increases the curve will be less square and the fill factor decreases.
What is a good fill factor?
If your system static and just read only, a default Fill Factor of 100 (or 0) is ideal. As there is no insert, update or delete, having all the pages filled up makes sense.
How can fill factor be minimized?
The key of reducing the reverse saturation current is lowering the recombination all over the cell. This will also make the ideality factor of the solar cell diode equals 1. Increased ideality factor will reduce the fill factor.
How do you increase fill factor?
To improve fill factor, one should select the material of low resistivity provided it follows all other requirements . i.e., optimum band gap around 1. 4 eV , low density of recombination centers, higher absorption coefficient and more built in potential.
How do you calculate fill factor?
The “fill factor”, more commonly known by its abbreviation “FF”, is a parameter which, in conjunction with Voc and Isc, determines the maximum power from a solar cell. The FF is defined as the ratio of the maximum power from the solar cell to the product of Voc and Isc so that: F F = P M P V O C × I S C.
What is SQL fill factor?
SQL Server Index Fill Factor is a percentage value to be filled data page with data in SQL Server. This option is available in index properties to manage data storage in the data pages. … Default value is 0 in SQL Server Index Property with each index of Tables, it prevents 100% storage to be filled in each data page.
What is silicon fill factor?
Fill factors (FFs) of ~0.87 have been obtained for crystalline Si (c-Si) solar cells based on Ag front contacts after rapid thermal annealing.
