Guide 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 Frequently Asked Questions about “Working mechanism of solar cells”
How do solar cells work?
Working Principle: The working of solar cells involves light photons creating electron-hole pairs at the p-n junction, generating a voltage capable of driving a current across a connected load.
What is the working principle of solar cells?
All the aspects presented in this chapter will be discussed in greater detail in the following chapters. The working principle of solar cells is based on the photovoltaic effect, i.e. the generation of a potential difference at the junction of two different materials in response to electromag-netic radiation.
What is solar power & how does it work?
While individual solar cells can be used directly in certain devices, solar power is usually generated using solar modules (also called solar panels or photovoltaic panels), which contain multiple photovoltaic cells. Such a module protects the cells, makes them easier to handle and install, and usually has a single electrical output.
How do solar cells produce a photovoltaic effect?
Solar cells exploit the optoelectronic properties of semiconductors to produce the photovoltaic (PV) effect: the transformation of solar radiation energy (photons) into electrical energy. Note that the photovoltaic and photoelectric effects are related, but they are not the same.
How do solar cells convert sunlight into electricity?
