Identifying the Cause of Voltage and Fill Factor Losses in Perovskite

The open-circuit voltage (V OC) and fill factor are key performance parameters of solar cells, and understanding the underlying mechanisms that limit these parameters in real devices is critical to their optimization vice modeling is combined with luminescence and cell current–voltage (I–V) measurements to show that carrier transport limitations within the cell

Open-Circuit Voltage

The above equation shows that V oc depends on the saturation current of the solar cell and the light-generated current. While I sc typically has a small variation, the key effect is the saturation current, since this may vary by orders of magnitude. The saturation current, I 0 depends on recombination in the solar cell. Open-circuit voltage is then a measure of the amount of

Shunt Resistance

The effect of shunt resistance on fill factor in a solar cell. The area of the solar cell is 1 cm 2, the cell series resistance is zero, temperature is 300 K, and I 0 is 1 x 10-12 A/cm 2.Click on the graph for numerical data. An estimate for the value of the shunt resistance of a solar cell can be determined from the slope of the IV curve near the short-circuit current point.

The above equation also demonstrates the importance of the ideality factor, also known as the "n-factor" of a solar cell. The ideality factor is a measure of the junction quality and the type of recombination in a solar cell. For the simple recombination mechanisms discussed in Types of Recombination, the n-factor has a value of 1. However

Fill factor analysis of solar cells'' current–voltage curves

A fill factor analysis can have these advantages. No fit is needed and fill factor and efficiency losses are directly obtained. By shifting the sunsVoc curve along the current density axis by J SC (1 sun) the pseudo illuminated curve and the virtually series resistance free pseudo fill factor pFF are obtained. The difference between FF and pFF then gives the fill factor losses

Impact of Fill Factor on Input Current Ripple of PV System

calculation of fill factor (FF) which is a main pointer of the photovoltaic panel performance. The fill factor is defined by the maximum power divided by the multiplication of the maximum voltage and the maximum current. For higher fill factor, the decline of the power curve becomes sharper and hence more power losses.

Fill Factor. One way to measure the performance of a solar cell is the fill factor. This is the ratio of the maximum power to the product of the open circuit voltage and short circuit current: The higher the fill factor the better. As a general rule, commercial PV cells will have a fill factor greater than 0.7.
