Solar cells
Definition
Solar cells are devices made from semiconductor materials that convert sunlight directly into electricity through the photovoltaic effect.
Analogy
Think of solar cells as tiny power plants on your rooftop. Just like how these power plants generate electricity from sunlight, solar cells harness the energy from the sun's rays and convert it into usable electrical energy for our homes.
Related terms
