This is the root cause why PID-affected solar cells cannot generate a maximum current. In addition, the examination of the backside (back sheet) for a solar cell impacted by PID is shown in Fig. 9d .
When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the "semi" means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal.
A photovoltaic (PV) cell is an energy harvesting technology, that converts solar energy into useful electricity through a process called the photovoltaic effect.There are several different types of PV cells which all use semiconductors to interact with incoming photons from the Sun in order to generate an electric current.
$begingroup$ Also note that a solar cell is a complex network of circuits - there are many local series and shunt resistances that influence the local voltage and current sources. These local voltages and currents are present when the cell is biased with illumination, regardless of the external operating condition (e.g. short-circuit, open-circuit).
