What is a Photovoltaic Cell?

Definition

A photovoltaic cell, also known as a solar cell, is a device that converts sunlight into electricity.

How Photovoltaic Cells Work

1. Absorption of Sunlight

When sunlight hits the photovoltaic cell, it is absorbed by the semiconductor material.

2. Generation of Electric Current

The absorbed sunlight excites electrons in the semiconductor, causing them to flow and generate an electric current.

3. Conversion of Solar Energy

The electric current is then captured and converted into usable electrical power for various applications.

Applications

Photovoltaic cells are commonly used in solar panels for generating electricity for residential, commercial, and industrial purposes.

Advantages of Photovoltaic Cells

1. Renewable Energy Source

Photovoltaic cells harness the power of sunlight, a readily available and renewable source of energy.

2. Environmentally Friendly

The use of photovoltaic cells produces clean energy and reduces the reliance on fossil fuels, thus minimizing environmental impact.

3. Low Maintenance

Once installed, photovoltaic cells require minimal maintenance, making them a cost-effective energy solution.

In conclusion, photovoltaic cells play a crucial role in harnessing clean and renewable energy from the sun, providing a sustainable and eco-friendly power source for various applications.
