Ask today's younger generation and they can tell you that Beiber boys and adult toys ... This is what solar panels are made of ... Well, kind of.
Justin Beiber the sun is a lot of young hearts, and when you shine on stage, the audience energy was electrifying. Sorry, we do not know how to capture this type of energy to use it to power our homes and businesses. So, for now, we're looking at solar panels, created by converting sunlight into energy into electricity to run our homes and businesses.
Well ... What exactly are solar panels made of? Well, so far mostly impure silicon crystals captured and used in solar cells.
You May be wondering why we speak of impure silicon crystals. This is because pure silicon is not electrically active. It's the impurities that create a tendency to lose or draw, or electrons. May light, including sunlight, contain energy. When sunlight hits an impure crystal silicon, an electric current occurs as the electrons get up and move. The electrons, freed from the absorption of light, bouncy, and then are forced to run in a certain direction to create electricity. By placing metal contacts on the top and bottom of what is called a PV (photovoltaic) cells, power is extracted. The term solar cell comes from a photo ... means light ... in combination with a galvanic electricity ... meaning. You've probably ... or know someone ... who has a calculator that is powered by solar cells. This and other small devices, including the arrangement of light, now are often powered by solar PV cells.
group of photovoltaic cells are connected electronically and placed in a box called the panel, and a group of plates are connected together is called a solar array.
takes a lot of solar panels to power the average American home. In an effort to reduce the number of records needed to produce enough energy to run home, or charge the battery for a car or generator, of materials other than silicon are being experimented with, and some success was achieved in thin film solar technology that uses less expensive crystals, such as copper-indium-gallium-selenide, which are designed in a flexible film. They are currently not as effective, however, such as silicon to create electricity.
And so ... looking for newer and better methods of creating solar power station goes on.
way back to the beginning of the solar cell is a long time ... and full of fossil fuel competition. For hundreds of years, however, mankind has sought to take advantage of solar energy, and we are still in progress ... Slowly but surely ... take advantage of this inexhaustible resource.
Romans, the next time the Greeks from the south-facing windows in their homes, open covered with glass or mica to catch and keep warm winter sun. They found the most optimal ways to utilize, passively, from solar energy.
Then, in 1861, a man named Auguste Mouchout, believed Europe would eventually run out of coal, developed the first sun-powered steam engine, non-passive use of solar energy. And, at this same time period, a man named William Gyrlls Adams discovered that the light is shined on selenium caused the material shed electrons, creating electricity.
However, the cost of capturing solar energy is cost-prohibitive for real development of this work, and non-passive solar innovations behind the ... through research Albert Einstein ... generate electricity from solar photovoltaic (PV) have advanced a notch with a second job in 1953 by Bell Laboratories.
and, even then, it was considered too expensive. Despite the success of scientists Daryl Chapin and Calvin Fuller's work in creating a measurable electrical current from solar photovoltaic cells, further progress in solar energy research and development cell is essentially lay dormant.
When she lay in the stagnant while the Arab oil embargo in 1973 showed the Western world's reliance on oil, the U.S. government has started again ... and desperate ... attempt to find a competitive, available energy alternatives to fossil fuels.
with subsidies for research, companies have begun to find ways to create a photovoltaic solar energy more economical. Japan rushed headlong into the PV energy in the solar roofs in the 1990s, which resulted in a significant reduction in global scale, the scale of the economy, the energy cost of PV cells.
panels for solar power today, however, is still more expensive than conventional sources of energy, somewhat difficult, and ... in some places ... relatively ineffective. lack of primary solar energy panel for normal household use and continue to prices of individual PV panels, a number of panels needed to generate large amounts of electricity.
However, in third world countries, especially in rural areas, there are many places where sunlight is abundant, the houses are small, and solar panels are very affordable, not just the individuals using them, but for the environment No left behind.
