Today Photovoltaic Solar Energy it is becoming more and more common and with more applications around the world.
Taking advantage of the solar energy It is not new but if the technology of the solar.
Physicist Alexadre-Edmond Becquerel is considered one of the first to recognize the photovoltaic effect in 1839, since the study of photovoltaic energy, electricity and optics generating important scientific contributions.
The first solar cell It was designed and built in 1883 by Charles Fritts with an efficiency of 1%, which used selenium with a thin layer of gold as a semiconductor. As its cost was high, it was not used for generate electricity but for other purposes.
The predecessor of the solar cells that are used today is the one created and patented by Russell Ohl in 1946 since he also used as semiconductor silicon.
The most modern silicon cells similar to the current ones were developed in 1954 at Bells Laboratories. These technological advances allowed the first commercial solar cells with 6% efficiency to appear on the market in 1957. They began to be used in space satellites in both the Soviet Union and the United States.
La solar energy for domestic use they appear in 1970 on a calculator and some small panels for the ceiling.
It was only in the 80s that more applications of solar energy became known and began to be used on the roofs of farms and rural areas.
With the improvement of Energy Efficiency of solar panels and the decrease in cost make them more used both in rural and urban areas and for commercial activities as well as in private homes.
Solar energy will be one of the main renewable sources of this century because it does not pollute and has improved its performance, making it commercially possible to use it to generate electricity in industrial quantities.
