Working Principle of Photovoltaic Cells. A photovoltaic cell essentially consists of a large planar p–n junction, i.e., a region of contact between layers of n- and p-doped semiconductor material, where both layers are electrically contacted (see below). The junction extends over the entire active area of the device.
Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy. This conversion is based on the principle of photovoltaic effect in which DC voltage is generated due to flow of electric current between two layers of semiconducting materials (having opposite conductivities) upon exposure to the sunlight [].

PV cell can be modeled using the equivalent circuit shown in Fig. 18.13.The irradiated PN junction of the A ill area generates a current of density J PV, with the P-type region charging positively and the N-type region negatively.Thus, the junction is biased in forward direction, and part I d of the generated current I PV = Aill J PV flows back through the diode D of …
Potential-induced degradation (PID) has been identified as a central reliability issue of photovoltaic (PV) cell modules. Several types of PID depend on the cell structure. Among those types, polarization-type PID, which is characterized by reductions in short-circuit current density (J SC) and open-circuit voltage (V OC), is the fastest PID ...
Solar cell is a device or a structure that converts the solar energy i.e. the energy obtained from the sun, directly into the electrical energy.
