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 working principle of a photovoltaic (PV) cell involves the conversion of sunlight into electricity through the photovoltaic effect. Here's how it works: Absorption of Sunlight: When sunlight (which consists of photons) strikes the surface of the PV cell, it penetrates into the semiconductor material (usually silicon) of the cell.
Chapter 4. The working principle of all today solar cells is essentially the same. It is based on the photovoltaic effect. In general, the photovoltaic effect means the generation of a potential difference at the junction of two different materials in response to visible or other radiation. The basic processes behind the photovoltaic effect are:
A silicon photovoltaic (PV) cell converts the energy of sunlight directly into electricity—a process called the photovoltaic effect—by using a thin layer or wafer of silicon that has been doped to create a PN junction. The depth and distribution of impurity atoms can be controlled very precisely during the doping process.
The key feature of conventional Photovoltaic PV (solar) cells is the PN junction. In the PN junction solar cell, sunlight provides sufficient energy to the free electrons in the n region to allow them to cross the depletion region and combine with holes in the p region. This energy creates a potential difference (voltage) across the cell.
The basic processes behind the photovoltaic effect are: collection of the photo-generated charge carriers at the terminals of the junction. In general, a solar cell structure consists of an absorber layer, in which the photons of an incident radiation are efficiently absorbed resulting in a creation of electron-hole pairs.
