The article provides an overview of photovoltaic (PV) cell, explaining their working principles, types, materials, and applications. It also outlines the electrical modeling, key operating characteristics, and performance curves of PV cells under varying environmental conditions. .
A PV cell is essentially a large-area p–n semiconductor junction that captures the energy from photons to create electrical energy. At the semiconductor level, the p–n junction creates a depletion region with an. .
The basic structure of a PV cell can be broken down and modeled as basic electrical components. Figure 4 shows the semiconductor p–n junction and the various components that make up a PV cell. The photon-to. .
While there are many environmental factors that affect the operating characteristics of a PV cell and its power generation, the two main factors are solar irradiance G, measured in W/m2, and temperature T, measured in degree Celsius (°C). The relation between these two factors and the PV operating characteristics can be modeled. .
The I–V curve of a PV cellis shown in Figure 6. The star indicates the maximum power point (MPP) of the I–V curve, where the PV will produce its maximum power. At voltages below the MPP, the current is a relative constant as voltage changes such that it acts similar to a current source. At voltages above the MPP, the voltage is relatively.
