Waves arising from electric and magnetic fields called electromagnetic waves. Electromagnetic waves are invisible to the human senses is light with a wavelength range of 300-700 nm (nanometers). Waves above 700 nm wavelength is infrared and ultraviolet below 300 nm is. Humans have a lot of use of energy contained in the wave elektomagnet since ancient times. But his own understanding of this new wave can be analyzed by us around the 10th century.
Over the development period, the use of electromagnetic waves by humans more frequently performed in daily life in accordance with the development of an understanding of the wave itself. The names such as Isaac Newton with Hypothesis of Lightnya, Christian Huygens wave propagation theory, the theory of electromagnetism Faraday, James Clerk Maxwell who managed to fix the wave propagation theory of Christian Huygens, a quantum theory of Max Planck, Albert Einstein and Louis de Broglie who stated that Light is a form of particle and wave-particle duality theory of wave has contributed greatly in making use of electromagnetic waves in everyday life.
Sunlight which is the emission of electromagnetic waves is one example of the many forms of energy that we can feel the earth and its resources have been used by us for centuries. Empowerment of sunlight energy in every age has increased along with the knowledge that we get and one of them is Solar Power Generation (PLTS) which utilizes the photon energy of sunlight into electrical energy.
Countries that passed by the equator and receives more solar heat than any other country, has enormous potential for developing solar power as an alternative to coal and diesel as a substitute for fossil fuels, clean, non-polluting, safe and unlimited supply.
Own solar cell material comprises a protective glass and transparent adhesive material that protects the solar cell materials from the environment, anti-reflection material to absorb more light and reduce the amount of reflected light, semi-conductor P-type and N-type (made from a mixture silicon) to generate an electric field, initial channel and the channel end (tebuat of thin metal) to send the electrons into electrical appliances.
How it works solar cells themselves are identical to the diode semiconductor devices. When the light touch with solar cell and absorbed by the semi-conductor material, the release of electrons. If the electrons can travel to the semi-conductor materials in different layers, there is a change sigma forces at the material. Style repulsion between the semi-conductor material, causing the flow of an electric field. And cause electrons to be channeled to the beginning and end for use in electrical appliances. Materials and methods are safe for the environment to make solar cells as a result of efficient electricity generating technology for alternative energy sources in the future society. Giving hope to us to manage in a more natural nature.
As soon as I came over to Solar Cells as an Alternative Energy | Global Warming Awareness I can only look at part of it, is this my internet browser or the web website? Should I restart? Cheers Iliana Shelton
