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 energy transformation occurs when solar panels are used to heat a building?
When solar panels are used to heat a building, the primary energy transformation involves converting solar energy into electrical energy through the photovoltaic effect. This electrical energy can then be used to power heating systems, such as electric heaters or heat pumps, which convert the electrical energy into thermal energy, warming the building. In some systems, solar thermal panels directly absorb sunlight and convert it into heat, which is then circulated to heat the building.
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. : )
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.
How do photovoltaic systems work to convert sunlight into electricity?
Photovoltaic systems work by using solar panels made of silicon cells to capture sunlight. When sunlight hits the cells, it creates an electric field that allows electrons to flow, generating electricity. This electricity can then be used to power homes and businesses.

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.
