How Do Solar Panels Convert Sunlight into Electricity?

Solar panels, made up of photovoltaic cells, use the photovoltaic effect to convert sunlight into electricity. But how do solar panels convert sunlight into electricity? When sunlight hits the solar panels, the photovoltaic cells absorb the photons from the sunlight. These photons then dislodge electrons from atoms within the cells, creating an electric current.

This conversion of sunlight into electricity is made possible by the unique properties of the semiconducting materials utilized in the solar panels. Among the most commonly used materials is silicon, which exhibits both conductive and non-conductive properties. As the sunlight strikes the silicon atoms, the energy from the photons excites the electrons, enabling them to move freely and generate an electric current.

The electric current produced by the solar panels is in the form of direct current (DC). However, since most household appliances and the electrical grid operate on alternating current (AC), an inverter is employed to convert the DC current into AC current. This ensures compatibility with various appliances and the electrical grid.

It is worth noting that the efficiency of the conversion process can vary depending on factors such as the quality of the solar panels, the intensity of sunlight, and the angle at which the panels are positioned. Typically, modern solar panels have an efficiency range of 15-20%, meaning they can convert approximately 15-20% of the sunlight they receive into usable electricity.
