Solar batteries (or "photo-powered" cells) are devices that convert the photograph from the sun (sunlight) into electricity.
Generally, solar cells, which contain both solar source and non-solar source (such as photons from incandescent bulbs), are called photocells.
Basically, this device should only perform two functions: the production of light of the charge carrier (electronic and poor) within the light absorbing material and separation of the charge carrier to the conductive contacts that transmit electricity. This transformation is called photocopy power effect, and the research field associated with solar cells is known as photocroic power. Solar batteries have many uses.
Historically, solar batteries have been used in remote power systems, perimeter satellites, and consumer systems where power from the grid is not available. Handheld Calculator or Watch, Remote Telephone, Water Pump
