The solar panels are made up of groups of Photovoltaic (PV) Solar Cells. These PV cells are semiconductor devices that are commonly made out of very pure silicon (Si) that when exposed to the sun they convert the Sun’s energy to direct current electricity. They are often simply called “solar cells”.
Semiconductors are materials that have unusual properties. They are not conductors like metals and are not insulators like many minerals or plastics. They have very unusual electrical properties that are not like either of these and this allows them to convert energy from the sun to electricity (captured photons release electrons that flow as electricity).
“Solar Panels” are simply groups of solar cells that have been packaged into a more practical arrangement. The solar panel construction protects the solar PV cells from the elements, like rain. It makes them physically more durable because they are protected on the top and bottom by other materials (glass, metal, plastics) and usually on the edges by metal frames. They also provide a solid method to secure them to their mountings.
