How a Solar Cell Works

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms—such as boron or gallium—that have one less electron in their outer energy level than does silicon. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or "hole" is created.

6 FAQs about [Photovoltaic cell p-n]

What is a photovoltaic (PV) cell?

A photovoltaic (PV) cell is an energy harvesting technology, that converts solar energy into useful electricity through a process called the photovoltaic effect. There are several different types of PV cells which all use semiconductors to interact with incoming photons from the Sun in order to generate an electric current.

What are photovoltaic cells & how do they work?

Photovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial applications.

What is a special photovoltaic cell?

Very special cells based on SiGe or quantum dots can then be used. A small niche application for special photovoltaic cells is the use in thermophotovoltaic generators, where instead of sunlight one uses thermal radiation from a hot body, typically with a temperature between 1000 °C and 2000 °C.

Are photovoltaic cells used for power over fiber (POF)?

While most photovoltaic cells are used for solar power generation, some are used for Power over Fiber (PoF), i.e. to deliver power in the form of light through an optical fiber (typically a multimode fiber). The requirements for the cell are very different from those for solar power generation:

Why is efficiency a design concern for photovoltaic cells?

Efficiency is a design concern for photovoltaic cells, as there are many factors that limit their efficiency. The main factor is that 1/4 of the solar energy to the Earth cannot be converted into electricity by a silicon semiconductor.

What is the most important layer of a photovoltaic cell?

The most important layer of a photovoltaic cell is the specially treated semiconductor layer. It is comprised of two distinct layers (p-type and n-type —see Figure 3), and is what actually converts the Sun's energy into useful electricity through a process called the photovoltaic effect (see below).
