: of, relating to, or utilizing the generation of a voltage when radiant energy falls on the boundary between dissimilar substances (such as two different semiconductors)
What is a short way to say photovoltaics?
photovoltaic. [ fō′tō-vŏl-tā′ĭk, -vōl- ]
What is an example of photovoltaic?
In the example shown below photovoltaic panels are used to produce electricity which powers a water pump, pumping drinking water from a well. … The power produced by the photovoltaic panels is also used to power a purification system, cleaning the water, removing dangerous impurities and harmful bacteria.
What does the word photovoltaics mean?

Why are photovoltaics used?
Photovoltaics are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons by the photovoltaic effect. Solar cells produce direct current electricity from sunlight which can be used to power equipment or to recharge a battery.
What are the most common photovoltaic cells used today?
6. What are the most common photovoltaic cells used today? 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.
Where is photovoltaic used?
The world solar market is dominated by photovoltaics, and most of the world’s PV market is serviced by crystalline silicon solar cells. Up until now PV has found widespread use in niche markets such as consumer electronics, remote area power supplies and satellites.
Is photovoltaic energy renewable?
Photovoltaic solar energy is a clean, renewable source of energy that uses solar radiation to produce electricity. It is based on the so-called photoelectric effect, by which certain materials are able to absorb photons (light particles) and release electrons, generating an electric current.
Where did the word photovoltaic come from?
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.
What is PV voltage?
An single photovoltaic solar cell can produce an “Open Circuit Voltage” ( VOC ) of about 0.5 to 0.6 volts at 25oC (typically around 0.58V) no matter how large they are. This cell voltage remains fairly constant just as long as there is sufficient irradiance light from dull to bright sunlight.
What is PV capacity?
The size or capacity of a solar photovoltaic (PV) system is the maximum electricity output the system can deliver.
