The Science Behind Photovoltaic Cells and Solar Panels


Harnessing the boundless energy of the sun has always been an aspiration for humankind. With the dire need to shift towards more sustainable energy sources, this aspiration has quickly turned into a reality. But how exactly do solar panels convert sunlight into electricity? Welcome to the wondrous world of photovoltaic cells.

The Basics of Photovoltaic Cells:

A photovoltaic (PV) cell, or solar cell, is a device that converts sunlight directly into electricity by a process called the photovoltaic effect. At its core, a PV cell is made up of semiconductor materials, typically silicon, which have properties allowing them to absorb sunlight and release electrons.

When photons (light particles) from the sun strike these semiconductor materials, they can release electrons from their atoms. Once these electrons are free, they can be directed and captured as electric current, effectively generating electricity.

How a Solar Panel is Structured:

solar panel or photovoltaic module is not merely one cell but a combination of many cells connected together. This assembly ensures that a significant amount of electricity can be generated. Here’s a basic breakdown:

  • Front and Back Layers: These are typically made of glass or clear plastic, offering protection without obstructing sunlight.
  • PV Cells: They’re arranged in a grid pattern, capturing sunlight and turning it into electricity.
  • Back Sheet and Frame: Offering structural support and protection against various weather conditions.

Converting Sunlight into Electricity:

  • Absorption: The first step in the solar panel installation process starts with ensuring optimal sunlight absorption. As sunlight hits the PV cell, the energy of the absorbed photons is transferred to electrons in the semiconductor material.
  • Creation of Electron-Hole Pairs: When these electrons gain enough energy, they break free from their normal position in the atoms to become a part of an electric current. This leaves behind what we call “holes”.

The Role of Save Energy UK:

If you’re looking to leverage the science of solar panels to your advantage, choosing the right solar installer is crucial. Save Energy UK has a distinguished reputation as a leading solar panel installation company. With keywords such as “solar panel installation near me” or “solar panels Poole”, you’re likely to come across this trusted name.

Beyond Solar Panels: The Solar Storage Battery:

The sun doesn’t shine all the time, so how do you ensure a steady power supply even during the night or cloudy days? Enter the solar storage battery. This technology allows you to store excess energy generated during sunny days to be used when sunlight is scarce.

Save Energy UK recognises the importance of this technology and incorporates it into their solutions, ensuring that users get the most out of their solar panel installations. So, alongside generating power, storing it efficiently is also a crucial aspect to consider.
