Photovoltaic Cell Working Principle. A photovoltaic cell works on the same principle as that of the diode, which is to allow the flow of electric current to flow in a single direction and resist the reversal of the same current, i.e, causing only forward bias current.; When light is incident on the surface of a cell, it consists of photons which are absorbed by the …
A solar module comprises six components, but arguably the most important one is the photovoltaic cell, which generates electricity.The conversion of sunlight, made up of particles called photons, into electrical energy by a solar cell is called the "photovoltaic effect" - hence why we refer to solar cells as "photovoltaic", or PV for short.

Arc detection in PV inverters must include a method for predicting the occurrence of arcing, either just before the occurrence of a sustained arc or very early in the in the lifetime of the sustained arc, where the source of the arc can be shut off. Then the PV Inverter can be shut down gracefully, preventing fires and if possible, damage to the inverters.
