Solar photovoltaic (PV) energy is a renewable and sustainable source of electricity that harnesses the power of the sun to generate electricity. The process of converting sunlight into electricity through solar PV panels involves several key steps that work together seamlessly to produce clean and efficient energy.
The photovoltaic effect starts with sunlight striking a photovoltaic cell. Solar cells are made of a semiconductor material, usually silicon, that is treated to allow it to interact with the photons that make up sunlight.
This conversion is called the photovoltaic effect. We'll explain the science of silicon solar cells, which comprise most solar panels. A photovoltaic cell is the most critical part of a solar panel that allows it to convert sunlight into electricity. The two main types of solar cells are monocrystalline and polycrystalline.
PV cells, or solar cells, generate electricity by absorbing sunlight and using the light energy to create an electrical current. The process of how PV cells work can be broken down into three basic steps: first, a PV cell absorbs light and knocks electrons loose. Then, an electric current is created by the loose-flowing electrons.
