Shunt resistance in solar cell
Did you know?
To understand the electronic behavior of a solar cell, it is useful to create a model which is electrically equivalent, and is based on discrete ideal electrical components whose behavior is well defined. An ideal solar cell may be modelled by a current source in parallel with a diode; in practice no solar cell is ideal, so a shunt resistance and a series resistance component are added to th… WebIn this study, the influence of temperature, solar irradiation, reverse saturation current, series and shunt resistance on PV cell are investigated …
WebApr 11, 2024 · The effect of shunt resistance and series resistance on solar cells performance was analyzed from 0 to 20 Ω cm 2 (Rs) and from 0 to 3000 Ω cm 2 (Rsh) . A significant impact of Rs on fill factor can be observed in Figure 7. Excessively high values (around 16 Ω cm 2) can also reduce the J sc. WebThe five parameters in this equation are primary to all single diode equivalent circuit models: : light current (A) : diode reverse saturation current (A) : series resistance () : shunt resistance () : diode ideality factor (unitless) For a photovoltaic module or array comprising cells in series, and assuming all cells are identical and under ...
