Solar Cell Operations How a Solar Cell Works
Solar Cell Operations are simple yet effective. The object matters which has the ability to emit electrons when a light is beamed on it are called photovoltaic cells or solar cells. These solar cells are instrumental in converting the Sun’s fusion energy into electricity.
These Solar cells are widely used in powering the calculator to satellites those orbit planets and exploration. These applications rely on sun light to generate electricity using Solar panels.
It’s important to understand the property parameters of a semiconductors to be able to learn about Solar Cells. These solar cells are made from the Silicon wafers, in which Silicon is a semi-conductor.
Solar Cell Operations Semiconductors carry the ability to behave as a conductor as well as an insulator.
Fusion energy from Sun brings in the multiple spectra radiations among which the visible light carries the charged energized particles called as Photons.
These Photons when they fall on the Silicon atoms in the Solar panel wafers the energy from photons are hit on silicon to discharge their electrons from the silicon atoms.
Solar Cell Operations An electrical disruption has to be created to siphon the discharged electrons to flow in same direction of the silicon wafers. This requires an imbalance in the cell to gather these electrons.
These silicon atoms are bonded very close and additional different types of conductors are introduced in their bonded structure, there by the spare electrons are collected, which is called n-type and the atoms which discharges these electrons are called as p-type semiconductors, which leave a ‘hole’ due to electron discharge.
The ‘p’ and ‘n’ type semiconductors are placed adjacent to each other there by the spare electrons in the n-type semiconductor get to fill in the p-type holes. Thus the n-type is positively charged and the p-type is negatively charged which generates an electric charge across the silicon cell. Since silicon is a semiconductor this step is made cyclic as it acts as an insulator creating this disruption.
Solar Cell Operations the photons from the light continue to hit the electrons in the silicon wafer or atom precisely potential difference is created in a cyclic steps, thus it helps to power the applications which are connected between these field charges which would act as a load.
