PV Gap

Edgar Said:

How does a solar panel work, and how do they separate the electrons?

We Answered:

Solar electric systems are commonly referred to as photovoltaic systems, “PV” for short. The photovoltaic effect (etymology: “photo” from the Greek meaning light; “voltaic” meaning voltage or electric current) is the ability of some materials (such as PV cells) to convert light energy from the sun into electricity. The PV cells are made up slices of silicon placed under a thin slice of glass. As photons from sunlight beat down onto the PV cells, they excite electrons in the silicon. Small wires on the silicon catch these electrons, and when joined together in a circuit an electric current is created.

how does a solar panel work?

We Answered:

It is due to the photoelectric effect. Electrons are emitted due to energy from the sunlight which is electromagnetic radiation. The electrons flow causing an electric current.

how does a silicon solar panel work?

We Answered:

oversimplified

light has energy and moves the electrons from one place to another. the silicon is an insulator so the electrons have to go through the circuit to get back where they "belong"
