Gallium arsenide is a semiconductor made from a mixture of gallium and arsenic. Cadmium tellurium CdTe cells: Arsenidne Gallium GaAs cells: In order for the valence electrons created free, he must get the energy that is greater than fotonaponwke equal to the bonding energy. Technology development [edit] The first modern solar cell photovoltaic been created in Until now, many developed materials that are commonly used silicon, then gallium arsenide, cadmium sulfide, cadmium telluride, and many others.

The corresponding annual electricity production is between 2. In Australia, for example, every year racing solar electric vehicles Eng. The characteristics of individual cells [edit] PV cells fotonaponnske made from silicon in several morphological forms, as well as monocrystalline, polycrystalline and amorphous.

Advantages of PV technology are that it is relatively clean technology.

It is suitable for use in multi-layered and highly efficient cells. The share of thin-film technology amorphous silicon, CdTe, CISdespite significant efforts in research has remained very modest, about 6.

Since these new materials are very expensive, the sunshine, the optical system of mirrors or lenses concentrate on small areas of expensive photovoltaic cells.

Postavljen je cilj da se ukupno ugradi MW fotonaponskih sustava do Koriste se na kao izvori napajanja na umjetnim satelitima i svemirskim stanicama. The photoelectric conversion PN spojuDa get electricity photoelectric effect should be directed fotoelektrona motion, or electricity.

Cadmium teleurid is a combination of elements: Economy [edit] Ccelije photovoltaic solar potential in EuropiZa now, the production of electricity from photovoltaic solar cells is not economical compared with other sources, if we do not take into account the incentives. Couples who incurred the impoverished area or are attracted to him, and it voids the P side of the semiconductor, the electrons of the N side of the semiconductor.

Other parameters [edit] Other parameters that have not yet mentioned, with an energy standpoint, it is time paying for energy. Part of the photon energy is consumed to electrons liberated from the influence of the atom which is attached, and the celijd part of the energy turns into kinetic energy, the now free electrons.

The ideal situation in Europe is to have a roof facing south with an angle of between 40 and 60 degrees, or, better yet, flat roof or the surface on which the panels can be adjusted at will.

Photon energy depends on its wavelength or the frequency. Energija vezanja predstavlja energiju kojom je elektron vezan za atom u nekoj od atomskih veza. Photovoltaic solar energy is one of the renewable energy sources. Koriste se i u dekorativne svrhe kao npr.

Due to the high price is used in space applications and systems with concentrated radiation which saves on the cells. They are used in decorative purposes such fotonaponsk in Zadar installing Sun Salutation. The particles of light called photons. Today this technology is blurring step in technology compared to multicrystalline silicon Mc-Si. During the solidification of materials creates crystal structures of different sizes whose boundaries appear mistakes, making the solar cell has a lower yield.

Energy photons can cwlije calculated from Einstein law, which reads: So the mature technology of PV cells in a crystalline semiconductor thin film.

These solar cells are called multi-layer solar photovoltaic cells Eng.
