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.

From LTWiki:
So when you included the
VREV
parameter, you changed your model to use the piecewise linear diode model instead of the usual nonlinear model. Your other parameters (IS
,XTI
, andBV
) are ignored and the piecewise linear model parameters that you didn't specify take their default values.. This could make a substantial change to the operating behavior of the diodes in your model.
