How do solar panels turn sunlight into electricity?

Solar panels create electricity through a process called the photovoltaic effect. Here is how it works in simple steps:

1. The Material: Solar panels are primarily made of silicon, a semiconductor. These cells are specially treated to create an electric field—one side is "n-type" (negative) and the other is "p-type" (positive).
2. Absorbing Light: Sunlight is made up of tiny packets of energy called photons. When these photons strike the solar cell, they transfer their energy to the atoms in the silicon.
3. Knocking Electrons Loose: This energy knocks electrons loose from their atoms. Because of the electric field created by the cell's design, these loose electrons are pushed in a specific direction.
4. Creating Current: When these electrons flow together in a path, they create a flow of electricity known as Direct Current (DC).
5. Inversion: Because most homes and appliances run on Alternating Current (AC), the electricity is sent through a device called an inverter, which converts the DC electricity from your panels into usable AC electricity for your home.

In short, the panels act like a bridge that turns the energy of light into a steady flow of electrons.
