As the times, the use of electromagnetic waves by human beings are increasingly being carried out in everyday life in accordance with the development of an understanding of the wave itself. Names such as Isaac Newton with Hypothesis of Lightnya, Christian Huygens to the theory of wave propagation, with the theory of electromagnetism Faraday, James Clerk Maxwell succeeded in improving the theory of wave propagation of Christian Huygens, a quantum theory of Max Planck, Albert Einstein and Louis de Broglie who stated that light is a particle and a wave with wave-particle duality theory has contributed greatly in making use of electromagnetic waves in everyday life.
Sunlight is an electromagnetic wave emission is one example of the many forms of energy that we can feel the earth and we have utilized its resources for centuries. Empowerment of the sun's light energy at every age increased along with the knowledge we get and one of them is a Solar Power Plant (PLTS) which utilizes the photon energy of sunlight into electrical energy.
Indonesia, a country crossed by the equator and receives more solar heat than any other country, has enormous potential for developing solar power plants as an alternative to coal and diesel as a substitute for fossil fuels that are clean, non-polluting, safe and supply is not unlimited. Various installations of solar cells has been widely used although only in some segments of society can afford.
The material itself consists of solar cells and protective glass 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, the initial channel and the channel end (tebuat of thin metal) to send the electrons into electrical appliances.
The workings of the solar cell itself is virtually identical to the semiconductor diode device. When light contact with the 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 on materials. Style repulsion between the semi-conductor material, causing the flow of an electric field. And causes electrons to be channeled to the beginning and end of the channel to be used on electrical appliances. Materials and safe way of working for the environment to make solar cells as a result of efficient power generation technologies for alternative energy sources in the future society. Gives hope to us to manage nature more "natural".
