pvdeg.letid.ff_green(voltage, temperature=298.15)

Calculates the empirical expression for fill factor of Si cells from open-circuit voltage.

See [1], equation 4.

Parameters:

• voltage (numeric) – Open-circuit voltage of the solar cell [V].

• temperature (numeric, default 298.15) – Temperature of the solar cell [K].

Returns:

numeric – Fill factor of the solar cell
