Who discover photo electric effect and what date?
The photo electric effect was explained by Einstein in 1905 when he theorized that light could transfer its energy like a particle and knock electrons out of metals. But the actual effect had been observed by a number of scientists since 1887, they just couldn't come up with a satisfactory theory that explained everything they observed. I believe he got the Nobel Prize for his photo electric effect theory, although he is more famous for his Relativity theories.
What is a semiconductor device that produce electric current through the photo-voltaic is an?
A semiconductor device that produces electric current through the photo-voltaic effect is a solar cell. When sunlight shines on the cell, it creates an electric current by releasing electrons from the material. This electric current can then be harnessed for various applications, such as generating electricity for homes or powering electronic devices.
What are photo-electrons?
Photo-electrons are electrons that are emitted from a material when it is struck by photons, typically in the form of light. This phenomenon, known as the photoelectric effect, plays a crucial role in various scientific and technological applications, such as in solar cells and photoelectron spectroscopy.
What is the term if cell the converts the sun energy into electrical energy by releasing electrons from silicon?
The term for a cell that converts sunlight into electrical energy by releasing electrons from silicon is a solar cell or photovoltaic cell. This process is known as the photovoltaic effect, where sunlight is converted directly into electricity.
How do photons create electrons?
Photons create electrons in two senses. In the first sense, they don't really create electrons but eject them: from a surface in the photo-electric effect or from atoms or molecules in photo-ionization. Observing the photo-electric effect was a key part of discovering quantum mechanics. In the second sense, an electron is created together with its anti-particle, a positron, when the photon collides with another particle. Particle-antiparticle creation requires a lot more energy than "photo-ejection". This is conversion of energy into matter, in this case matter with a rest mass of just over a million electronvolts (in mass-equivalent units according to Einstein's E=mc^2). So the photon (and target particle) need to have kinetic energy of that amount for electron-positron pairs to be created.
Electrons ejected in the photoelectric effect are called?
Photo electrons. So current due to these photo electrons is named as photo electric current.
What is the ability of light to cause electron movement and electric current?
The ability of light to cause electron movement and electric current is known as the photoelectric effect. When photons of light strike a material, they can transfer their energy to electrons, causing them to be ejected from the material, which can then result in the generation of an electric current.
