How to calculate the saturation current of silicon photovoltaic cells
Determining solar cell parameters and degradation rates from …
Agilent DC electronic loads (6060B) measure IV curves roughly every 40 s, from sunrise to sunset. These curves are translated into time-series of the short-circuit current I sc, open-circuit voltage V oc, fill factor FF, cell efficiency η, series resistance R s, and shunt resistance R sh for each panel. Due to a voltage drop along the junction line …

Light Generated Current
The generation of current in a solar cell, known as the "light-generated current", involves two key processes. The first process is the absorption of incident photons to create electron-hole pairs. Electron-hole pairs will be generated in the solar cell provided that the incident photon has an energy greater than that of the band gap.
