Methods in this module

This modules puts together the functions for calculating the figures of merits of solar cells

pypvcell.fom.ff(voltage, current)

Calculate the fill factor from an I-V curve

Parameters:

• voltage (np.ndarray) – voltage array
• current (np.ndarray) – current array

Returns:

fill factor (in numerics)

pypvcell.fom.isc(voltage, current)

Calculate the short-circuit current of an I-V curve
