How Does A Solar Cell work? A Definitive Guide


Solar Cells

The solar cell has revolutionized how we harness solar energy. Previously only plants, animals, and few things placed directly under the sun can benefit from the unlimited power of the sun. But with the development of solar cells, we gained the capability to use it for other purposes beyond the limitations. If you’re curious about these things, then here is a thoroughly-researched, yet brief guide for you on the solar cell. You can take inspiration from it to further your knowledge on this topic.

What Is A Solar Cell?

A solar cell is an electronic device that converts the cosmic rays received from the sun directly into electricity. This electricity can then be consumed or stored for future use in a battery. Solar cells are small in size, generally as big as the size of your palm. These solar cells bundled up to form larger units known as “Solar modules.” Furthermore, these solar modules bundled together to form much larger groups called solar panels. Generally, solar panels used in large-scale projects. So in that regard, a solar panel installed on your roof is made up of hundreds, if not thousands, of small solar cells.

Material Used

A solar cell made up of Silicon, which is a semiconductor. These allow the flow of electricity through the battery, which is not possible in the case of conductors. In the case of semiconductors, too, they do not conduct electricity normally but do so in certain situations. Which, in this case, is the falling of sun rays. Two types of Silicon components are used to create a single cell.

A solar cell is similar to a battery cell that designed to generate electricity. But how does precisely it achieves this feat? As mentioned earlier, the two types of Silicon used, which are doped or individually treated with another material. One is doped in such a way that it has the number of electrons. It is called N-type Silicon. The other doped to contain a lesser amount of particles, and this is called P-type Silicon

When both of them are fused, they create a junction. It doesn’t let electrons from one component flow to the other. But when sunlight falls on the cell, the particles get enough energy to cross the junction and flow through the circuit. It generates electricity which we can then use to power our homes or cars or electrical devices. It is why the solar cell is also called a photovoltaic cell, and the phenomenon is called the photoelectric effect.

Application And Uses

Solar cells find their application in sectors of fields such as automotive, electronics, homes, real estate, but for one single goal. And that is to convert solar power to electrical power and generate electricity. You can find one cell in your neighborhood or even in your home. So the next time you come across one, you will know who a solar cell works. That will make you appear smarter and confident in your approach.
