Previous studies have been focused on the voltage of bypass diode and Isc(Short Circuit Current) of the influenced solar cell. The bypass diode starts working when it gets the reversed applied voltage. Previous studies have only concentrated on Isc of the influenced solar cell and Imp of PV module to explain the bypassing performance. However, usually the PV module and inverter are installed together. The inverter has the MPPT(Maximum Power Point Tracking) function for best performance. We can expect the bypassing point is regulated by MPPT function of inverter.
We already complete the analysis about the relationship between internal structure of PV module and bypassing point. but we just used ideal solar cell. so, we need to apply real solar cell.
In this paper we show the simulation results for bypass diode in PV module with different Fill Factor. We experiment the relationship of the bypassing point and the Fill Factor of PV module. As the result, the more high Fill Factor cells were used, the earlier bypassing performance happens. Vmp is greater, with 68% Fill Factor.
