..Solar cells are described as being photovoltaic, irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.
...... Main uses of solar cell
.. Solar Power Farms
United States government requirements including the Renewable Portfolio Standards have mandated that electric utilities produce a significant fraction of their power through renewable sources such as solar energy. Facilities such as the Agua Caliente Solar Project in Arizona produce electricity for local communities. When its final phase is completed, the power plant will have more than 5 million solar cells, producing a total of 290 megawatts of power. At the time of publication, the United States has 9,360 megawatts of electrical generating capacity from photovoltaic cells.
* Off-Grid Power
In addition to producing electrical power for the commercial grid, solar cells see wide use as an off-grid energy source. For example, many traffic, emergency and construction road signs use solar cells for power, reducing the need for gasoline-powered generators for remote and mobile uses.
*Rooftop Solar Panels
Many commercial and residential buildings have solar panels that produce electricity; in most cases, the building gets its power primarily from a conventional utility connection, but the solar cells generate enough power to reduce the owner’s conventional electric use and the associated electric bill. The solar panel connects to a power management system that automatically switches to the utility when solar power isn’t available.
* Satellites
Communications satellites require an electric power source that is lightweight, lasts for years, and works in the vacuum of space. Because solar energy is abundant above the earth’s atmosphere, photovoltaic cells have proved an ideal solution for powering satellites. They generate electricity continually without the need for battery replacements or fuel; this is a nearly-absolute requirement for satellites, as their maintenance is impractical and prohibitively expensive.
