What electricity does a solar cell use
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
Solar cells use the sun''s energy to free electrons. These electrons move towards the cell''s front, creating more charge on its front. This makes a voltage potential. When electrical conductors on the cell take in these electrons, they form an electric current. Connecting the cell to a device or the grid allows this current to flow for use.
