We delve into the photovoltaic effect, which is at the heart of solar cell functionality, converting sunlight directly into electrical energy. The basic structure and operation of solar cells are elucidated, including the role of semiconductor materials and their interaction with incident light to generate electron–hole pairs.
In order to produce current a solar cell must first convert the incoming photons to free carriers by the absorption and generation process. In this process, a photon passing through the semiconductor is absorbed and in doing so gives its energy to an electron in the valance band.
Today, photovoltaic technology is a major industry with applications in a wide range of sectors, including residential and commercial buildings, transportation, and power generation . The continued growth of the industry is expected to play a key role in the transition to a more sustainable energy system .
The current produced in a solar cell is directly proportional to the intensity of radiation and is governed by the photoelectric effect, i.e., with an increase in the intensity, the current increases. However, an increase in the temperature of the solar cell reduces its voltage.
Because the output voltage and current of a solar cell are both temperature dependent, the actual output power will vary with variations in ambient temperature. A photovoltaic (PV) array is built by interconnecting various solar cells together and I-V characteristics are then plotted to determine its efficiency and other parameters .
