6 FAQs about [What interface does the solar cell have ]

Why is a solar cell free to move inside the silicon structure?

Instead, it is free to move inside the silicon structure. 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 solar cells?

Solar cells are the electrical devices that directly convert solar energy (sunlight) into electric energy.

What is the theory of solar cells?

The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device.

How is a solar cell constructed?

The construction of a solar cell is very simple. A thin p-type semiconductor layer is deposited on top of a thick n-type layer. Electrodes from both the layers are developed for making contacts. A thin electrode on the top of the p-type semiconductor layer is formed. This electrode does not obstruct light to reach the thin p-type layer.

Why do solar cells have a special structure?

Due to their special structure and the materials in solar cells, the electrons are only allowed to move in a single direction. The electronic structure of the materials is very important for the process to work, and often silicon incorporating small amounts of boron or phosphorus is used in different layers.

How do solar cells work?

Solar cells can be arranged into large groupings called arrays. These arrays, composed of many thousands of individual cells, can function as central electric power stations, converting sunlight into electrical energy for distribution to industrial, commercial, and residential users.
