Description

Series of utilities for fitting non-ideal diode models to JV data. The utilities can be used to fit a JV curves of a solar cells with the following equations:

Dark non-ideal diode model:

$$J = J_0\left[\exp\left(-q\frac{V-R_s J}{n k_b T}\right)-1\right] + \frac{V-R_s J}{R_{sh}}$$
The method used to calculate the dark JV is based on the the study by Ortiz-Conde et al. published in Solid-State Electronics 44 (2000) 1861-1864.\

Light non-ideal diode model:

$$J = -J_{ph} + J_0\left[\exp\left(-q\frac{V-R_s J}{n k_b T}\right)-1\right] + \frac{V-R_s J}{R_{sh}}$$ For the light JV, the method is based on the study by Jain et al. published in Solar Energy Materials & Solar Cells 81 (2004) 269–277
