Solar Cells

Solar cells are in fact large area semiconductor diodes. Due to photo voltaic effect energy of light (energy of photons) converts into electrical current. At p-n junction, an electric field is built up which leads to the separation of the charge carriers (electrons and holes). At incidence of photon stream onto semiconductor material the electrons are released, if the energy of photons is sufficient. Contact to a solar cell is realized due to metal contacts. If the circuit is closed, meaning an electrical load is connected, then direct current flows. The energy of photons comes in "packages" which are called quants. The energy of each quantum depends on the wavelength of the visible light or electromagnetic waves. The electrons are released, however, the electric current flows only if the energy of each quantum is greater than WL - WV (boundaries of valence and conductive bands).

Be rewarded with feed-in tariffs. If your solar system generates more power than you need, you have the potential to be reimbursed for any electricity your system feeds back into the grid, thanks to State Government feed-in tariffs (FITs). A feed-in tariff is a buy back rate paid on a net basis for any excess power your system produces that you don't first use in your home. Feed-in tariffs are designed to encourage more Australians to generate their own electricity and vary by state.

Solar energy for industry

INTRODUCTION
Sunlight is a clean, economical and safer alternate source to fossil fuel and batteries. It is a free and inexhaustible fuel source. It reduces electricity costs, as well as the number of batteries used into landfills. As it is environment friendly so many industries prefer solar energy as compared to fossil fuel.

Solar Power
Solar power has been used by industries for a long time but its demand increased in 1970 when the governments and industries were forced to use other sources of energy than oil. After research photovoltaic cells came into existed and solar energy took place of fossil fuel.

Solar energy platform in industries.
It is an open area of space with a large number of great big magnifying mirrors pointing towards the sun. These systems concentrate sun rays to a surface and heat the fluid that flows from one location to another through the common pipeline on which they are focused. This type of arrangement heats oil that is in the pipes which is then used to heat water to create steam. Oil is used because it can maintain heat and the steam obtained are used to drive the generators to get electricity.
Such an arrangement will be able to heat oil that is coming through pipes which will then be used to heat up water that will create steam. Oil is commonly employed as it can by character preserve the heat very well and at last the steam manufactured may be used to run generators to get electrical energy. Pressure which is involved in heating up the liquid can also be used to run many machines. The heat can increase the size of the fluid against the pistons of the motor which results in mechanical power. This power can be used to run generators which will then provide electricity.

Advantages of solar energy

• Reduced energy budget
As the energy is being used from a natural source it reduces the budget of a company.

• Reduced CO2 emissions
Solar source of energy is environment friendly there is no carbon emissions caused during the conversion of solar energy.

• Greater energy independence

• The solar energy is abundantly available on earth and it can be used for many years for the generation of energy.

• Solar power plants can be connected to the big existing present power sources to create a hybrid power system for energy formation in dry summer days.

• Solar power panels are long-lasting and do not need much repairs. Usually life time of solar power panels is up to 20 to 25 years, which give good reason for the initial cost of solar panel.

• Solar power supply systems are not at all noisy, they are soundless and efficient in their working hence protects pollution. ,.

• Solar panels are capable of linking with other type electric generators for e.g. gas turbines, wind, hydro etc. Batteries can also be charges for constant electricity supply.

• It will minimize amount of carbon-monoxide, greenhouse gasses and other pollution released into air. The more electricity from solar panels is used the more it is beneficial for environment to reduce pollution from our atmosphere.

Solar energy for industry

Industrial Solar Energy

Solar energy is the energy that comes from the sun. Every day the sun gives an enormous amount of energy to the earth. The sun emits amount of energy in one second more than ever used from the beginning of life on earth.

Applications and its work

Storing the energy generated from heat and light makes these PV cells work more reliable. They save the power and then reused when needed. These PV cells are used in switches, telephones, television and almost every electric equipment. A physical process called the photovoltaic effect is actually the change of the energy from sun-light into electrical potential energy by a photo voltaic cell(solar cell). Photovoltaic cells are used to in situations where they are more profitable than other power generation methods. Sometimes, they are used as photo detectors.

The photovoltaic cells store the heat and light which comes from the sun and make it useable in place of electricity. These PV cells can also be used in street light as they save all the energy in day light and then make it workable in night for longer period and the major character tics of this PV cells is that it stores the energy and then make it reuse as an alternative of electricity. Another method is used to increase the amount of electricity which is being generated by PV cells is that the huge amount of silicon layers are combined together from what the are called PV arrays. These PV arrays are mostly used to power the electric equipment in homes and offices. They are very much useful in supplying power or electricity to the remote places where there is no source of generating electric powers. The PV cells are useful because it stores all the power which comes from sun in form of heat and light and then this power is saves in these cells and then it used in night and cloudy whether because at night there is no sun light and in cloudy whether the sun light is dim, but these PV cells have the quality to save that power so that it can used be used in contingency. The PV cells are different from these cells because the PV cells have more storing and long live capacity on the other hand the disposable cells have shorter life and they don’t have long storage capacity.

Solar photovoltaic’s global market trend

As we know that the world have recognized that the best alternative of fossil fuel is solar energy because it have many advantages and less side effects because of which the trend of PV has came in global market. The manufacturing of PV is increasing as according to latest report that its manufacturing is almost reaching 48 percent average per year since 2002 and it has turn out to be the world fastest growing energy technology. Rough approximation says that almost 90 percent of generating capacity is consisting of grid-tied electrical system. This type of installation can be ground mounted or it can be on roof tops or walls and it have a particular name called building integrated photovoltaic or for in short terms BIPV.

Photovoltaic is the field of technology which tells that how the application of solar cell is utilizing light and heat from the sun in the electricity form so that it can be used as an alternative to the electricity which is being formed from fossil fuel.
