noun Physics. (used with a singular verb) a field of semiconductor technology involving the direct conversion of electromagnetic radiation as sunlight, into electricity.
What are the 2 root words in photovoltaic?
The term photovoltaics derives from the Greek word phōs meaning light and the word volt, named by italian physicist Alessandro Volta (1745-1827). Photovoltaics is a science, which examines light-electricity conversion, respectively, photon energy-electric current conversion.
How do you spell photovoltaics?
The -voltaic part of photovoltaic comes from the name of Alessandro Volta, inventor of the electric battery. Thus, unlike photoelectric cells, which use electricity for certain small tasks, photovoltaic (or PV) cells actually produce electricity.

Is photovoltaic the same as solar?
As you can see, photovoltaic cells and panels are both integral, closely connected parts of your solar PV system. Photovoltaic cells are the main component that makes up a solar panel, while solar panels are a vital component that makes up a solar system.
Which is the correct definition of photovoltaics?
Wikipedia Definition. Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. … PV installations may be ground-mounted, rooftop-mounted, wall-mounted or floating.
What are photovoltaic materials?
Materials used in photovoltaic devices are usually silicon (monocrystalline, polycrystalline or amorphous), gallium arsenide, metal chalcogenides and organometallics. Recently, mesoscopic solar cells have made an impact in commercial markets.
How do you use photovoltaic in a sentence?
Photovoltaic sentence example

- A photovoltaic battery can convert solar light into usable energy.
What is PV cell and PV module?
Photovoltaic cells are connected electrically in series and/or parallel circuits to produce higher voltages, currents and power levels. Photovoltaic modules consist of PV cell circuits sealed in an environmentally protective laminate, and are the fundamental building blocks of PV systems.
What is photovoltaic glass?
Solar Photovoltaic (PV) glass is a glass that utilizes solar cells to convert solar energy into electricity. It is installed within roofs or façade areas of buildings to produce power for an entire building. In these glasses, solar cells are fixed between two glass panes, which have special filling of resin.
What are the most common photovoltaic cells used today Mcq?
Unveiled by Bell Labs in 1954, silicon cells were the very first successful photovoltaic (PV) technology, and they remain the most common PV cells in use today.
What is the difference between photodiode and solar cell?
A photo diode is made to detect light quickly whereas a solar cell is made to collect energy from light. They are both typically silicon diodes, but modified to meet their different requirements. A photo diode has to be fast, which means low capacitance, which means small area of silicon.
What do you understand by photovoltaic technology define and explain using an example?
Photovoltaics is the direct conversion of light into electric power using semiconducting materials such as silicon. … Photovoltaic, therefore, means light-electricity, describing exactly the photovoltaic phenomenon where you can directly convert light into electricity.
