Solar panels are a remarkable technology that converts sunlight into electricity, providing a clean and renewable source of energy. Understanding the science behind this conversion process involves delving into the physics of photovoltaic (PV) cells, which are the fundamental components of solar panels.
And there is another way to use this abundant energy source: photovoltaic (photo = light, voltaic = electricity formed through chemical reaction) solar cells, which allow us to convert sunlight directly into electricity.
An electric current is created when enough electrons are stimulated. Depending on the material, the frequency necessary to trigger the effect can vary. In photovoltaic solar panels, semiconductors are the photoelectric medium used to convert sunlight to electricity.
In conclusion, the energy transformation in a solar panel is a process that involves the absorption of sunlight, the conversion of photons into an electric current, and the output of the electricity that is produced.
Photovoltaic cells are based on a related phenomenon called the photovoltaic effect, and they convert light directly into electricity. Let’s look at how. Most photovoltaic cells are made of silicon, an element that is at the heart of all modern electronics.
The solar panels are designed to absorb sunlight, which is made up of tiny particles of energy called photons. As the photons from the sunlight hit the surface of the solar panel, they are absorbed by the material that makes up the panel. This material is typically made of silicon, which is a semiconductor that has the ability to absorb photons.
