The panel itself produces DC and if it is connected to mains electricity it needs a separate converter to change the current to AC.

What is principle construction and working of solar cell?
Photovoltaic Cells: Converting Photons to ElectronsThe solar cells that you see on calculators andsatellites are photovoltaic cells or modules (modules are simply a group of cells electrically connected and packaged in one frame). Photovoltaic, as the word implies (photo = light, voltaic = electricity), convert sunlight directly into electricity. Once used almost exclusively in space, photovoltaics are used more and more in less exotic ways. They could even power your house. How do these devices work? Photovoltaic (PV) cells are made of special materials called semiconductors such as silicon, which is currently the most commonly used. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely. PV cells also all have one or more electric fields that act to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off to use externally. For example, the current can power a calculator. This current, together with the cell's voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce. That's the basic process, but there's really much more to it. Let's take a deeper look into one example of a PV cell: the single-crystal silicon cell.
Names of active transducers?
thermocouple, photoelectric transducer, photovoltaic cell, piezoelectric transducer
Is photo voltaic cell is an active transducer?
A photovoltaic cell is an active transducer. This is commonly referred to as a strain gauge or simply known as a solar panel.
Can you make a photovoltaic cell at home?
Yes and no. There used to be a hobby kit with all the materials (ceramic tube electric furnace, one bare silicon wafer, dopant chemicals, metal plating chemicals, wafer scoring scribe, wire, and chemical trays) and instructions to make 8 small silicon photovoltaic cells. But it has been out of production for more than 25 years. It would be very difficult (but not completely impossible) to replicate something similar to this kit and make your own photovoltaic cells now, but certain materials would probably need to be purchased in prohibitively large quantity for an individual.
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 is the kind of cell used to turn sunlight into electric current?
It is called a photovoltaic cell.
What word is for the definition the kind of cells used to turn sunlight into electric current?
It is called a photovoltaic cell, also called solar cells.
What does a photovoltaic cell do?
It produces a DC voltage as a result of incident sunlight
What is primary and secodary cell in term of physics?
a primary cell is an electric cell that produces current by an irreversible chemical reaction
What causes solar power?
Sun is the main cause of solar power.When sunlight hits a solar cell, also known as a photovoltaic cell, that energy can be transformed into electric current.
What device produces an electric current by converting chemical energy into electrical energy?
A cell aka battery.
What is the device that turns solar energy into electrical energy?
A photovoltaic cell.A photovoltaic cell.A photovoltaic cell.A photovoltaic cell.
A device that produces an electric current by converting chemicalenergy into electrical energy?
A chemical cell or strings of cells called a battery.
What type of energy is photovoltaic?
Photovoltaic refers to a type of solar cell or panel that produces a voltage directly from sunlight and does not require the use of batteries to transform sunlight into usable power.
Can a led work as a photocell?
If you mean a photovoltaic cell, then no. A photovoltaic cell requires a metalloid to function. The metalloid such as silicon can take on two different types: negative silicon or positive silicon which provides for a slight electric potential. Photons emitted from the sun excite electrons on the surface of the silicon and induce a current between the two plates.
What part of an electrical cicuit produces the electric current?
Either the cell e.g. a battery, if one is included in the circuit. Or a generator such as a dynamo
How does an electric current produce light?
By heating a metal wire called a filament. In a light bulb (lamp) the electric current flows through a tungsten filament which glows white hot giving off light.
