A photovoltaic cell is an electronic device that converts the energy in the solar radiation that reaches the earth in the form of light (photons) into electrical energy (electrons) thanks to the photoelectric effect. Major milestones in the history of the development of these cells, include:
And all this is possible thanks to an essential component: the photovoltaic cell. A photovoltaic cell is an electronic device that converts the energy in the solar radiation that reaches the earth in the form of light (photons) into electrical energy (electrons) thanks to the photoelectric effect.
Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy. These photons contain varying amounts of energy that correspond to the different wavelengths of the solar spectrum. A PV cell is made of semiconductor material.
Working principle of Photovoltaic Cell is similar to that of a diode. In PV cell, when light whose energy (hv) is greater than the band gap of the semiconductor used, the light get trapped and used to produce current.
The characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies: Efficiency: Determines the ability to convert sunlight into electricity, typically measured as a percentage. Open-Circuit Voltage (Voc): Maximum voltage produced when not connected to any external load.
Its primary function is to collect the generated electrons and provide an external path for the electrical current to flow out of the cell. The characteristics of Photovoltaic (PV) cells can be understood in the terms of following terminologies:
Effect of Light Intensity
Changing the light intensity incident on a solar cell changes all solar cell parameters, including the short-circuit current, the open-circuit voltage, the FF, the efficiency and the impact of series and shunt resistances.

Photovoltaic effect
In addition to the direct photovoltaic excitation of free electrons, an electric current can also arise through the Seebeck effect. When a conductive or semiconductive material is heated by absorption of electromagnetic radiation, the heating can lead to increased temperature gradients in the semiconductor material or differentials between materials. These thermal differences in turn may generate a voltage because the electron energy levels are shifted differently in different are…
