Photovoltaic cells, also known as solar cells, are the building of solar panels. These cells are responsible for converting sunlight into electricity through a process called the photovoltaic effect. In this article, we will explore how photovoltaic cells work through an animation.
The Photovoltaic Effect
The photovoltaic effect is the process by which photovoltaic cells convert sunlight into electricity. When sunlight hits the surface of a solar cell, it excites the electrons in the cell, causing them to flow and create an electric current. This process is the fundamental principle behind how photovoltaic cells work.Construction of a Photovoltaic Cell
A typical photovoltaic cell is made of several layers of materials, including a semiconductor material such as silicon. The top layer of the cell is made of a transparent conductive material, which allows sunlight to pass through and reach the semiconductor layer. When sunlight hits the semiconductor layer, it causes the release of electrons, which in turn creates an electric current.Animation of the Photovoltaic Process
To better understand how photovoltaic cells work, let’s take a look at an animation of the photovoltaic process. In the animation, we can see the sunlight hitting the surface of the solar cell and exciting the electrons in the semiconductor layer. As the electrons flow, they generate an electric current, which can then be used to power electrical devices.
