DC electricity can be used to charge batteries that power devices that use DC electricity. . A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load. Way out in space there's a gargantuan ball made up of gas, mostly helium and hydrogen.
