Why Does the I-V Characteristic Curve Invert in PC1D Simulations?

Click For Summary
SUMMARY

The forum discussion centers on the use of PC1D, a widely utilized solar cell modeling program, to simulate the I-V characteristic curve of photovoltaic silicon. The user encountered an issue where the short-circuit current (Ib) was recorded as -3.183, leading to a flipped I-V curve. The user seeks guidance on how to adjust the simulation parameters to achieve a positive short-circuit current value, which is critical for accurate solar cell performance analysis.

Hi All,

I am using PC1D (is the most commonly used of the commercially available solar cell modelling programs) when I tried to simulate PV silicon to see I-V characteristic curve the curve flip as you can see attached file. My question how can I make short_circuit Ib positive value?


Results :
Short_circuit Ib : -3.183
Max base power out : 1.362 watts
Open-cicuit Vb : 0.5920 volts

Thanks in advance
