Voltage is generated in a solar cell by a process known as the "photovoltaic effect". The collection of light-generated carriers by the p-n junction causes a movement of electrons to the n -type side and holes to the p -type side of the junction.
PV Cell or Solar Cell Characteristics. Do you know that the sunlight we receive on Earth particles of solar energy called photons.When these particles hit the semiconductor material (Silicon) of a solar cell, the free electrons get loose and move toward the treated front surface of the cell thereby creating holes.This mechanism happens again and again and more …
The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation. The photovoltaic effect is closely related to the photoelectric effect, where electrons are emitted from a material that has absorbed light with a frequency above a material …
Photovoltaic cells work on the principle of the p-n junction. A p-n junction is a boundary between a p-type semiconductor (where the majority charge carriers are positively charged holes) and an n-type semiconductor (where the majority charge carriers are negatively charged electrons).
