What are solar cells?
Q: What are solar cells?
A: Solar cells are semiconductor devices that convert light to electricity.
Q: What are some applications of solar cells?
A: Solar cells are used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth-orbiting satellites and space probes, consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications.
Q: How are solar cells starting to be used more recently?
A: More recently, solar cells are starting to be used in assemblies of solar modules connected to the electricity grid through an inverter, often in combination with net metering.
Q: Why are solar cells seen as an important technology for sustainable energy supply?
A: Solar cells are regarded as one of the key technologies of solar energy towards a sustainable energy supply.
Q: What do solar cells convert light to?
A: Solar cells convert light to electricity.
Q: Where have solar cells been used in situations where power from the grid is unavailable?
A: Solar cells have long been used in situations where electrical power from the grid is unavailable, such as in remote area power systems, Earth-orbiting satellites and space probes, consumer systems, e.g. handheld calculators or wrist watches, remote radiotelephones and water pumping applications.
Q: In what ways are solar cells used in combination with net metering?
A: Solar cells are starting to be used in assemblies of solar modules connected to the electricity grid through an inverter, often in combination with net metering.
