Because of the complicated political situation in Europe and the different policies of each Member State, there is no coordinated approach to renewable energy sources.

What the fotonaponskoj technology burden on the environment is the production of PV cells, and the use of toxic materials such as cadmium.

In this way the PV cells are effective at very little or no profit. Time paying for energy is the time that PV cells must work to produce electricity which is needed for its production. Linking cells in a larger whole [edit] Linking cells can celuje derived in two ways: It is suitable for use in multi-layered and highly efficient cells. 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 fotlnaponske the panels can be adjusted at will.

Since some of the materials for making PV cells, toxic, this would represent a risk to the environment.

Applying [edit] Photovoltaic solar power plant Serpa in Portugal, 11 MW power Photovoltaic solar cells supply the International Space Station electric energijomPrimjena PV solar cells today is widespread and is becoming more widespread. Za izradu tako velikih kapaciteta bilo bi potrebno vrlo mnogo materijala. In fact, one of the most common application of PV solar cells is the power supply devices, industrial facilities, homes where there is no electricity in locations that are remote from the power system or a photovoltaic system is cheaper to build than to build installations for the supply of electric power systems.

Due to the high price is used in space applications and systems with concentrated radiation which saves on the cells. From this standpoint, the energy barrier should be as small as possible, but when it would not be, there would be no electric field, or what functions they perform.

When the sun is very high in the sky summerits rays travel through the atmosphere faster at shorter distances, than when the low in the sky winter. However, the quality and the ability to celiije is not such that this technology took the lead in the near future. Valence electrons are associated with the atom, while the free electrons can move freely.

Each material used part of the spectrum of solar radiation. Production of these cells is economically efficient as compared to monocrystalline. There are attempts to PV cells used in transport. In this way solar cells produce power around 0. The following factors will affect the amount of sunlight, which affect the efficiency of photovoltaic panels: Valentni elektroni vezani su uz atomdok se slobodni elektroni mogu slobodno gibati. In many countries, but also in Croatia, there are incentives and privileges for renewable energy.

To create such large capacity would require a lot of material. Today this technology is blurring step in technology compared to multicrystalline silicon Mc-Si.

In this way, build the modules as an image that is displayed to the left of the text. The share of thin-film technology amorphous silicon, CdTe, CISdespite significant efforts in research has remained very modest, about 6. For the production of monocrystalline Si cells is required absolutely pure semiconducting material. So far, the usefulness of PV solar cells to about forty percent. Energija fotona ovisi o njegovoj valnoj duljini odnosno o frekvenciji.

For example, a silicon PV cell has a maximum spectral sensitivity for a wavelength of nm, ie the best absorbs light and wavelength.

In this way it is possible to achieve higher utility, even higher than the theoretical benefits in the use of only one material. Fotonaponzke electrons, obtained by the photoelectric effect are also called fotoelektroni. Sve do nedavno Koriste se i u dekorativne svrhe kao npr. Suitable for use in thin PV modules due to the physical properties and low-cost manufacturing technology.

Devices that are taking place photovoltaic energy conversion are called solar cells. When using only one material for the production of PV solar cells much of the energy spectrum of photons remains unused.

Thin-film technology enables significant savings in materials, more flexible installation of PV cells, since they can be bent.

It has high absorption and the required thickness of only a few microns to absorb the sun’s rays. Liquid silicon is poured into blocks which are then cut into slabs. The equation that describes this process as follows: The photoelectric conversion PN spojuDa get electricity photoelectric effect should be directed fotoelektrona motion, or electricity.

Photovoltaic solar cells made of thin technology filmaRazvoj PV technology in recent years, driven by strong market development, has been extensively amended.
