Solar cells:

             Solar energy can also be converted directly into electricity by solar cells. A solar cell also called a photocell is made from a silicon wafer.

             When sunlight falls on a solar cell, it converts the light directly into electrical energy. Solar cells are used in calculators, watches, and toys. Large numbers of solar cells are wired together to form solar panels.

             Solar panels can provide power to telephone booths, lighthouses, and scientific research centers. Solar panels are also used to power satellites.
