Solar cell. Close-up of the surface of a solar (photovoltaic) cell, which converts light into electrical energy. The cell is made from a semi- conductor such as silicon (as here). When light hits it it releases electrons, which are converted into an electrical current. A grid of wires collects the electrons. This is a polycrystalline (amorphous) cell, made from numerous small silicon crystals. This type of cell is less efficient than a single-crystal cell, but is far cheaper to manufacture. Solar power is an environmentally-friendly energy source. It does not use up limited resources and does not release toxic waste products. Magnification unknown.
