Hint: A solar cell, also known as a photovoltaic cell, is an electrical device that uses the photovoltaic effect, a physical and chemical phenomena, to convert light energy directly into electricity. It's a type of photoelectric cell, which is described as a device with electrical properties that change when exposed to light, such as current, voltage, or resistance. Individual solar cell devices are frequently used as the electrical components of photovoltaic modules, also known as solar panels. The highest open-circuit voltage of a typical single junction silicon solar cell is around 0.5 to 0.6 volts.
Complete answer:
Regardless of whether the source of light is sunlight or artificial light, solar cells are classified as photovoltaic. They can be employed as a photodetector (for example, infrared detectors), detecting light or other electromagnetic radiation within the visual range, or measuring light intensity in addition to generating energy.
Three essential characteristics are required for the operation of a photovoltaic (PV) cell.The absorption of light that results in the formation of electron-hole pairs or excitons.Charge carriers of opposing kinds are separated.Separate carriers are extracted and sent to an external circuit.Current density is the amount of electric current moving per unit cross-section area and is measured in amperes per square metre. The higher the current density in a conductor, the higher the current density.
However, the current density varies in various sections of an electrical conductor, and this phenomenon occurs with higher-frequency alternating currents. A magnetic field is always created by an electric current. The magnetic field becomes more powerful as the current becomes stronger. The principle of signal transmission is based on the creation of an electromagnetic field by varying AC or DC.
Hence, a photovoltaic cell's current density ranges from 40 to 50 \[mA\text{ }c{{m}^{2}}\].
Note: The fill factor is equal to the product of the open-circuit voltage and short-circuit current divided by the actual maximum attainable power. This is an important factor to consider while assessing performance. In 2009, the fill factor of most commercial solar cells was more than 0.70. The average grade B cell size was between 0.4 and 0.7.Because cells with a high fill factor have a low equivalent series resistance and a high equivalent shunt resistance, less of the cell's current is lost to internal losses.
