Solar cell | Definition, Working Principle, & Development
WhatsAppWhat Is A Solar Cell? A solar cell is a device that captures the energy of the sun in the form of direct sunlight and converts it into electrical energy. A solar cell is also known as a photovoltaic cell, which implies that it converts the photons present in the light into a voltage difference (which essentially means "electrical power").
