The cell's unique structure, consisting of two distinct semiconductor layers – one positively charged (p-type) and one negatively charged (n-type) – creates an electric field at their junction. This field drives the freed electrons to flow in a specific direction, generating an. 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. It provides mechanical support and serves as a base for depositing the active layers of the cell. Such cells, which can power everything from calculators to cars (our example will be a house), have several components. The photovoltaic cell is the basic component of any PV panel. It converts solar radiation into electrical energy.
