How Do Solar Panels Turn The Sun Energy Into Electricity

A solar cell is made from two layers of silicon one doped with a tiny amount of added phosphorus n type.

How do solar panels turn the sun energy into electricity. An active solar energy source has two major applications. The solar panels are made of solar cells. A solar panel is a semi conductor device which will produce an electrical voltage and current if light falls on it. Strikes the semiconductor light is converted into electricity that flows through the circuit.

They are attached by wire to a circuit. P for positive the doping ingredients create extra electrons in the n type layer and holes missing electrons in the p type layer. As soon as the light is removed the solar cell stops. This electricity can then be used to supply renewable energy to your home or business.

They can do this because of something called the photovoltaic effect. N for negative the other with a tiny amount of boron p type. Just like a sandwich it s the. Solar cells are what make collecting solar energy possible.

They extract the power generated within the solar cell and conduct it to an external circuit. It is actually a giant diode a one way valve for electricity and when light falls on it this gives some electrons enough energy to jump through the valve and the only way they can get back is to flow around the circuit doing useful work. The bread on either side consists of thin strips of metallic electrodes. In most solar systems solar panels are placed on the roof.

But how do solar panels do this. It s used on the solar panels that adorn rooftops cars calculators and even planes. In all reality it s actually quite simple. With this energy system the solar energy from the sun is converted into electricity by using an intermediate circuit photo voltaic.

An ideal site will have no shade on the panels. And the solar panels that you see on an increasing number of roofs do something similar converting light into electricity. On its own a single. Photovoltaic technology directly converts light from the sun into electricity.

What s in a solar cell. Solar powered photovoltaic pv panels convert the sun s rays into electricity by exciting electrons in silicon cells using the photons of light from the sun.
