Photovoltaic Devices
Photovoltaic devices are electronic devices that convert sunlight directly into electricity. They are made of semiconductor materials, such as silicon, and consist of one or more thin layers that absorb photons and release electrons, creating a flow of electricity. Photovoltaic devices are used in a variety of applications, including spacecraft, satellites, and space stations, where they provide power for communication, navigation, and scientific instruments. They are also used on Earth to generate electricity for homes, businesses, and utilities. The efficiency of photovoltaic devices has improved significantly over the years, and they are now a cost-effective and reliable source of renewable energy.
