What does photovoltaic mean simple?
: 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) Other Words from photovoltaic Sunshine and Photovoltaic Example Sentences Learn More About photovoltaic.
Is photovoltaic the same as photoelectric?
While the photoelectric effect involves light photons knocking electrons out of a material completely, the photovoltaic effect involves photons from a light source knocking electrons only out of their atomic orbitals, but keeping them in the material; this allows them to flow freely through the material.
What two words make up photovoltaic?
When you start to investigate solar energy one of the first words you will come across is “photovoltaic”. This word is made up of two separate “mini-words”: ‘photo’ and ‘voltaic’. ‘Photo’ comes from an ancient Greek word, ‘phos’, which means ‘light’.
What is photoconductive cell?
Photoconductive cells are light-sensitive resistors in which resistance decreases with an increase in light intensity when illuminated. These devices consist of a thin single-crystal or polycrystalline film of compound semiconductor substances.
What is the difference between photoelectric cell and photovoltaic cell?
In fact, they involve the emission of electrons by the absorption of energy from light. … The main difference between the two processes is that in the photoelectric effect, the electrons are emitted to the space whereas, in photovoltaic effect, the emitted electrons directly enter a new material.
Do photovoltaic cells use the photoelectric effect?
Photovoltaic energy is a clean, renewable source of energy that uses solar radiation to produce electricity. It is based on the photoelectric effect—the emission of electrons when electromagnetic radiation (i.e. light) hits a material. … The type of material used has an impact on how efficient the solar cell is.
What is the photoelectric effect in solar panels?
The photoelectric effect is the scientific principle that makes solar power possible. The photoelectric effect is the principle referring to when electrons are released by photons making an electrical current, which is what makes it possible for the harvesting of electricity through the use of solar cells.
