Solar panels work by converting incoming photons of sunlight into usable electricity through the photovoltaic effect.
The working principle of solar panels is the principle of generating electricity. There is a potential difference in the p-n line layer. The electric field is directed towards the layer p. When the n-plate surface is exposed to the Sun photons erupt an overabundance of electrons. Those will accept the forces of the electric field.
At the heart of a solar panel's ability to generate electricity is the photovoltaic (PV) effect. Discovered in 1839 by French physicist Edmond Becquerel, the PV effect is the process by which solar cells within the panel convert sunlight into electricity.
The conversion of sunlight into electricity involves the fundamental principle of the photovoltaic effect within solar cells. These cells, typically made of semiconductor materials like silicon, are the core components of solar panels. When incident light reaches the p-n junction of a semiconductor, a process called photogeneration occurs.
Although the terms 'solar array' and 'PV (Photovoltaic) system' are often used interchangeably, they have distinct meanings. The solar array is just one component of a PV system. Moreover, a solar panel is not the same as a solar module; a panel typically consists of a string of several modules.
