Solar cell operation, Energy production Animations

An animation of electricty being generated in a solar cell A solar cell then, is a piece of semiconductor made from a p-type layer and an n-type layer connected by an external circuit. The most common materials used for this purpose are silicon doped with boron and phosphorus, although there are many other combinations that are used, Solar cell animation

Electrons and holes moving to create a p-n junction When semiconductor material, regardless of its doping, is exposed to light of sufficient energy, the light will give some electrons in the crystal enough energy to escape from the lattice and move around. This leaves a hole behind that also moves

Photoelectric effect A freshly polished, negatively charged zinc plate looses its charge if it is exposed to ultraviolet light. This phenomenon is called the photoelectric effect

Photo-electric effect study the photo-electric effect with three different materials, sodium, cesium, and silver

Photovoltaic Cells

Photovoltaic Electricity This animation illustrates how a solar cell cut from a single crystal of Silicon is able to convert sunlight into electricity. The bottom layer is doped with a P type material such as Aluminum, Gallium or Indium to produce holes. The N type layer is doped with Phosphorous, Arsenic or Antimony to create mobile electrons

Solar cell operation Photovoltaic Electricity

Solar cell operation solar cells convert light energy into electrical energy either indirectly by first converting it into heat, or through a direct process known as the photovoltaic effect. The most common types of solar cells are based on the photovoltaic effect, which occurs when light falling on a two-layer semiconductor material produces a potential difference, or voltage, between the two layers

Solar cell how a Solar cell works, Solar cell animation

Solar cell animation When energy is received from the sun in the form of photons, some of the photons are absorbed near the junction, freeing the electrons and holes in the silicon. The photons of light give enough energy for the electrons to cross the junction, where they can be picked up on the metal contacts on the surface of the solar cell and move through an external circuit. After moving through the external circuit and performing work (such as powering a lamp or motor) the electrons return to the solar cell

Solar cell animations and calculations

Solar Cells Photodiodes and solar cells work in the reverse sense to LEDs. If a photon of sufficient energy strikes the valence band in the transition region ( also known as the diffusion region ) of the diode, an electron can be promoted to the conduction band by the photoelectric effect leaving a hole in the valence band. The internal electric field ensures these separate and are available to an external circuit

Daylight Hours Explorer Shows the hours of daylight received during the year for an observer at a given latitude. This is an important factor contributing to the seasons

Light Rays The angle the light rays from the sun make with the surface of the earth is called the angle of incidence. When there is a large angle of incidence, the light rays are spread out over a large area. The strength of the incoming beam is weakened as far as a small portion of the surface is concerned. When the light bears straight down on a surface, it isn't spread out at all and the surface feels the full intensity of the beam

PVGIS Solar Irradiance Data provides monthly and yearly averages of global irradiation at horizontal and inclined surfaces, as well as other climatic and PV-related data (Linke turbidity, ratio diffuse/global irradiation and optimum inclination angle of the surface)
