Photovoltaic/Solar Cell

What is a solar cell

A solar cell, also known as a photovoltaic (PV) cell, is a device that converts sunlight directly into electricity using the photovoltaic effect. These cells are typically made from semiconductor materials like silicon. When light strikes a solar cell, it generates a flow of electrons, creating an electrical current. Solar cells are the fundamental building blocks of solar panels used for harnessing solar energy.

In simple terms, a solar cell means a device that turns sunlight into usable electricity.

Importance of solar cell

The importance of solar cells lies in their ability to generate clean, renewable energy that reduces reliance on fossil fuels and lowers greenhouse gas emissions. Solar cells enable sustainable power for homes, industries, and remote locations, helping to lower energy costs and support a greener, environmentally friendly energy future. Their scalability and simplicity make them essential for advancing renewable energy and combating climate change.

Uses of solar cell

Common uses of solar cells include:

• Generating electricity for residential and commercial buildings
• Powering remote systems such as satellites and space missions
• Supporting off-grid applications in rural and isolated areas
• Charging electric vehicles and portable electronic devices
• Running solar-powered streetlights, traffic signals, and signage
• Providing electricity for water pumping and irrigation systems in agriculture

Powering portable solar generators for emergency or outdoor use

Examples of solar cell

Some practical examples of solar cells are:

• Solar cells in rooftop panels that power homes and offices
• Photovoltaic cells in large solar farms supplying electricity to the grid
• Solar-powered calculators and watches using small photovoltaic cells
• Solar cells in satellites providing energy in space
• Portable solar chargers for smartphones, laptops, and other devices
• Solar streetlights powered by photovoltaic cells in urban and rural areas
