A solar cell consists of a layer of p-type silicon placed next to a layer of n-type silicon (Fig. 1). In the n-type layer, there is an excess of electrons, and in the p-type layer, there is an excess of positively charged holes (which are vacancies due to the lack of valence electrons).
What are the main parts of a solar cell?
The four major components of a solar energy system are the panels, inverter(s), racking and solar battery storage unit(s) (if desired). Solar panels are the most visible element of your system, which is why you’re likely the most familiar with it. They are, in essence, the “face” of solar.
What are the 5 main components of a solar cell?
There are 5 key components in a home solar panel system: solar panels, an inverter, an electrical panel, the power grid, and the sun. In this blog, we’ll walk you through how each component works together to create a complete solar panel system.
Where is solar cell used?
Historically solar cells have been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth orbiting satellites, consumer systems, e.g. handheld calculators or wrist watches, remote radio-telephones and water pumping applications.
Why silicon is used in solar cell?
Silicon is one of the optimum semiconductors that is used for solar cell production because of its superior electronic properties, optical properties, thermal properties and mechanical as well as environmental properties. In addition to its availability, manufactureability, and cost.
