Photovoltaic Cells
Photovoltaic cells, also known as solar cells, are devices that convert sunlight directly into electricity. They are made of semiconductor materials, such as silicon, and work by absorbing photons from sunlight, which knock electrons in the semiconductor material into a higher state of energy, creating a flow of electricity. Photovoltaic cells are used in a variety of applications, including powering spacecraft, providing electricity to remote locations, and generating electricity for homes and businesses. They are a key technology in the field of renewable energy and are becoming increasingly important as the world seeks to reduce its reliance on fossil fuels.
