Eē = ½ · m · v 2 = E y - W = h · f – W Where Eē is the energy of an electron, v is the speed of an electron, m is the mass of an electron, Eᵧ is the energy of the light quantum, and W is the work function, which is a constant dependent on the metal.W is the energy that is required to release an electron from a metal to produce photoelectrons.
Photovoltaic cells are semiconductor devices that can generate electrical energy based on energy of light that they absorb.They are also often called solar cells because their primary use is to generate electricity specifically from sunlight, but there are few applications where other light is used; for example, for power over fiber one usually uses laser light.
Here, we present an analysis of the performance of ''champion'' solar cells (that is, cells with the highest PCE values measured under the global AM 1.5 spectrum (1,000 W m −2)) for different ...
