Solar cells are often referred to as the heart of solar panels. Without a collection of solar cells, it would not be possible to generate photovoltaic energy. In this article, we will explain what a solar cell is and why it is essential.
What Is a Solar Cell?
A solar cell is a small scientific device designed to convert sunlight into electricity. We can call them Mini Power Plates that get activated when the sun shines. Combining multiple cells forms PV panels. These panels collect the heat from the sun’s rays and generate the energy needed to power electric appliances and entire homes.
Solar cells are the foundation of PV energy systems, and their reliability and efficiency are key to producing clean, renewable PV energy.
Which Elements Are Used in Solar Cells?
The primary element used in PV cells is silicon. Silicon is a natural material found in sand and rocks. It is ideal for cells because its features allow them to absorb sunlight’s heat and convert it into electricity efficiently.
To enhance the performance of silicon, some manufacturers add small amounts of other elements like phosphorus and boron. These elements help the cell handle electricity better and improve its ability to produce power in the long run.
This is how silicon-based PV cells are built. Australian Premium Solar India Ltd manufactured panels also consist of Silicon-based cells.
What is silicon wafers?
Solar cells are primarily made of silicon wafers that are thin slices of pure & raw silicon. These are carefully processed to maximize their ability to capture even less sunlight. The silicon itself is very durable and affordable which makes Silicon wafers even stronger & long-lasting.
However, as technology advances, alternative materials are also being explored for specialized PV cells. Despite these innovations, silicon remains the most popular material due to its proven efficiency and long-lasting performance.
How Do Solar Cells Work?
Solar cells work on a scientific principle called the PHOTOVOLTAIC (PV) effect. This PV technology is the process of converting solar energy into electricity.
Here’s how it works:
Sunlight Hits the PV Cell: Sunlight contains energy in tiny particles called photons. When these photons strike the surface of a PV cell, they transfer their power to the electrons in the silicon.
Electrons Get Activated: The energized electrons get activated and start moving, creating a flow of electrical energy.
Electricity Is Produced: This movement of electrons generates an electric current, which can then be used to power devices and appliances.
Since a single PV cell produces only a small amount of electricity, many cells are connected to a PV panel. These panels generate enough energy to meet the needs of homes, businesses, and even large-scale industries.
Why Solar Cells Are Essential?
PV cells are at the heart of the PV revolution, making it possible to capture the limitless energy of the sun. These solar cells’ life shell is also long-lasting making them a reliable choice for users.
