What is a solar panel and how does it work? (Ultimate 101 Guide)
A solar cell is also known as a photovoltaic (PV) cell. This name is appropriate since the word photo means "light", and voltaic refers to "electricity". In fact, a solar cell is the fundamental unit of the solar panel. Solar cells are available in a variety of sizes and types depending on the demands of the user.
Solar cell | Definition, Working Principle, & Development
Solar cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The majority of solar cells are fabricated from silicon—with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms.
