Solar Cells

Solar cells are photodiodes with very large surface areas. This allows them to be more sensitive to incoming light and yield more power than usual photodiodes. A single solar cell may provide up to 0.5V that can supply 0.1A when exposed to bright light.

Questions

• What are solar cells?
• How do solar cells work?
• What are the benefits of solar cells?
• What are the limitations of solar cells?

Answers

• Solar cells are photodiodes with very large surface areas. They convert light energy into electrical energy.
• Solar cells work by the photovoltaic effect. When light hits a solar cell, it creates an electric field that separates electrons and holes. This creates a current that can be used to power devices.
• The benefits of solar cells include their clean and renewable energy source, their low maintenance, and their long lifespan.
• The limitations of solar cells include their low efficiency, their high cost, and their dependence on sunlight.
