The Science Behind Solar Cells


Now let’s take a look at how solar cells work and how they convert sunlight into electrical energy. Understanding the solar cell structure is essential to comprehend this process. Solar cells, also known as photovoltaic cells, are made up of several layers of semiconducting materials. The most commonly used is silicon. These layers are carefully designed to absorb sunlight and generate an electric current.

The process begins with the absorption of photons from sunlight by the solar cell. These photons transfer their energy to electrons in the semiconducting material, causing them to become excited and break free from their atomic bonds. This creates electron-hole pairs, where the hole is a positively charged location where an electron used to be.

The electric field within the solar cell then separates the electron-hole pairs, pushing the electrons towards one electrode and the holes towards the other. This flow of electrons creates an electric current, which can be harnessed and used as electrical energy.
