Series and shunt resistances in solar cells are parasitic parameters, which affect the illuminated current–voltage (I–V) characteristics and effi ciency of cells. Very high values of series resistance (R s) and very low values of shunt resistance (R sh) reduce short-circuit current density (J sc) and open-circuit voltage (V oc), respectively.
Such problems often arise in effect of leakage current resistance or parallel resistance of a photovoltaic cell. In this paper, influence of a cell shunt resistance in a general photovoltaic cell on the fill factor (FF) has been analyzed. Variation in shunt resistance considerably changes the output power.
A MATLAB program has been developed to study the variation in current-voltage (I-V) curve of the PV cell on the effect of shunt resistance. The algorithm for comparing the design data and experimental values of fill factor has identified the best efficiency solar cell with the effect of shunt resistance.
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.
In this paper the low light performance of solar cells and modules is investigated with a simple approach. Only three parameters (1) the series resistance, (2) the shunt resistance and (3) the ideality factor are used similar as it was already shown by Grunow et al. in 2004.
The minor role of the R s is in line with findings for silicon solar cells which report that the series resistance only limits the low-light performance if limitations due to the parallel resistance are negligible (Litzenburger et al., 2014). ...
