Photovoltaic (PV) materials and devices convert sunlight into electrical energy. What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power.
Solar power is a clean, renewable energy source. So, think of solar power as using the sun’s energy to create electricity without the downsides, like pollution or greenhouse gases. When we harness the sun’s energy, solar PV systems produce electricity without emitting carbon dioxide (CO2) or other harmful pollutants.
PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.
Experimental PV cells and PV cells for niche markets, such as space satellites, have achieved nearly 50% efficiency. When the sun is shining, PV systems can generate electricity to directly power devices such as water pumps or supply electric power grids.
When we harness the sun’s energy, solar PV systems produce electricity without emitting carbon dioxide (CO2) or other harmful pollutants. This helps combat climate change and reduces air pollution, benefitting public health and our environment. Additionally, solar power doesn’t use much water, which is great for conserving this precious resource.
An electric current is created when enough electrons are stimulated. Depending on the material, the frequency necessary to trigger the effect can vary. In photovoltaic solar panels, semiconductors are the photoelectric medium used to convert sunlight to electricity.
