Free QuoteThe series resistance is alumped parameter value which represents the summation of several loss mechanisms in a solar cell. For example, losses due to resistance introduced in cell solder bonds, emitter and base regions, cell metallisation, and cell-interconnect busbars all contribute to the value of Rs ( Green, 1998 ).
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.
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 article shows effect of series (R s) and shunt resistances (R s h) on solar cell parameters to enhance the photovoltaic performance of f-PSCs. Single diode model has been employed to analyzed the results. Better morphology has been achieved by using antisolvent.
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.
Reduced shunt resistance ( R s h) in solar photovoltaic cells can lead to module degradation and failure. An experimental method has been developed to simulate progressive degradation by artificially lowering the shunt resistance. A linear model has been developed which relates reduced R s h to module open-circuit voltage and maximum power output.
