I want to simulate the reverse breakdown behavior of a two diode model solar cell in SPICE.
The diodes configurations without considering the breakdown voltage are as below:
.model diode d( Is=1.5e-10, xti=3) .model diode2 d(Is=1.77e-6, n=2, xti=3)
With the given diodes configurations, I can simulate all characteristics before the breakdown voltage point.
By adding the breakdown voltage point to the diode model, I cannot see the curve in forward bias anymore and it does not work properly.
.model diode d( Is=1.5e-10, xti=3, vrev=15, BV=15) .model diode2 d(Is=1.77e-6, n=2, xti=3, vrev=15, BV=15)
In short, when I add the code for reverse breakdown voltage point, my diode does not work properly in forward bias! Please help me with this problem.
