Photovoltaics means to generate electricity from sunlight. Tiny photovoltaic cells are used in devices such as calculators, to save battery power. Larger systems are used to provide electricity to devices or homes that are far from the interconnected electric network.

What is a photovoltaic device?
A photovoltaic device is a device that absorbs light (infrared, visible, and ultraviolet) and produces an electric potential. Photovoltaic devices operate by using the energy from an absorbed photon to excite an electron (or hole) across a p-n junction. While longer wavelengths (microwaves) and shorter wavelengths (X-rays) of electromagnetic energy can also be used to produce electric potentials, the devices that do this are not considered photovoltaic because they operate on different principles.
What is photoelectric switch?
Switches, used mainly for situations such as sentry devices or outside lights. The generation of electricity by the photovoltaic cell when light is present.
What principle is used in hydraulic systems?
Many principles are used in hydraulic systems the basic being the Pascal's law
Why are hydraulic systems used in machinery such as bulldozers and backhoes while pneumatic systems are used for things such as opening and closing bus doors?
I think it is because hydraulic systems are stronger than pneumatic systems. if you know that is wrong then get an expert. : )
Why are hydraulic systems used in excavators?
Hydraulic systems are very powerful and flexible. Due to excessive speed and power are used in the excavation.
Which makes photovoltaic systems especially useful?
They generate electricity......
Can photovoltaic cells store energy?
Photovoltaic cells generate electricity when exposed to sunlight. They do not store energy themselves, but the electricity they produce can be stored in batteries or used immediately.
How is photovoltaic used in a sentence?
Photovoltaic cells can convert sunlight into energy.

Solar energy is produced by?
Solar energy is produced by the sun's rays, which are converted into electricity through the use of photovoltaic cells or solar thermal systems. Photovoltaic cells directly convert sunlight into electricity, while solar thermal systems use sunlight to generate heat that can be used to produce electricity.
