Silver paste is used in 90 percent of all
crystalline silicon photovoltaic cells, which are the most common type of solar cell. Around the world, solar
arrays are being tested for large and small-scale electricity production. In Europe, photovoltaic systems
commonly are used to power private homes and local businesses. South Korea is constructing photovoltaic electric
power plants to provide significant sources of electricity for the nation’s power grid. In the United States,
nationwide stores such as Macy’s and Wal-Mart are installing photovoltaic systems on the roofs of their
buildings to contributing up to 40 percent of their power needs. Photovoltaic systems are simple and provide
immediately useful power with no pollution.

Silver is used in another way to generate
electricity by reflecting and concentrating solar energy onto collectors containing salts which are used to run
generators. Near Barstow, California, for example, 1,926 silver-coated mirrors reflect solar heat onto
black-coated stainless steel tubes atop a 300-foot tower. This heats the tubes and the nitrate salt inside them
to over 1050 degrees F. The scalding hot salt is then piped to boilers, turning water to steam which drives
steam turbines that run electric generators. They generate electricity to power 10,000 homes.
