Understanding Solar Cell Efficiency

To understand solar cell efficiency, you need to know how solar cells convert sunlight into electricity. Solar cells work by absorbing photons from the sun and using them to create an electric current.

The efficiency of a solar cell is determined by how well it can convert sunlight into usable electricity.

How Solar Cells Convert Sunlight into Electricity

Converting sunlight into electricity is a process that involves the use of solar cells. These cells are made from various materials, such as silicon or thin-film semiconductors, which have unique properties that allow them to efficiently convert sunlight into electrical energy.

When sunlight hits the solar cell, it excites the electrons in the material and creates an electric current. This conversion process can be visualized through a nested bullet point list:

  • The first sub-list includes:

  • Sunlight shining down on a solar panel.
