Solar Cells

A solar cell (or photovoltaic cell) is a device that converts solar energy (sunlight) directly into electrical energy using the photovoltaic effect. It is made of semiconductors like silicon (Si), sometimes doped with phosphorus and boron to form a p–n junction. When sunlight falls on the junction, electrons move from the n-type to the p-type region, creating an electric current. Solar cells are clean, renewable, and require very little maintenance. They are widely used in:

• Solar panels
• Calculators
• Satellites
• Streetlights
