Photovoltaics is a revolutionary technology that has changed the way many things today work. This technology has gained immense popularity in terms of green and clean energy. The most prominent application of this technology is seen in the form of solar cells which are being extensively used for production of power, all across the globe. The major advantage of using Photovoltaic technology is environmental preservation through production of clean energy. This blog post will offer more information on the development in Photovoltaic applications.
Understanding Photovoltaics
The basic principle of photovoltaics is rooted in semiconductors. There are some materials which react to light in a very special way (cadmium-tellurium, crystalline silicon, etc.). When light of a threshold strength strikes the surface of these materials, electrons are ejected (this is technically known as photoelectric effect in physics). This creates a cavity in the atomic structure of the material, which makes the rest of the electrons start “flowing”, which creates an electric current.
Application of photovoltaics
The above stated process forms the basis for production of clean energy. A lot of what happens in a photovoltaic system depends on the way that particular system has been manufactured. Since this involves constant exposure to light over a long period of time, the materials used to manufacture a solar panel need to be very rugged. In order to achieve a highly efficient and quality system, it is necessary to ensure that assembly of parts (right from the semiconductors of a solar cell to the panel) are assembled properly. Even the slightest mistake can cause drastic deviations in efficiency and life of a system. There are international standards, like the International Electrotechnical Commission (IEC), which define the benchmarks of manufacturing quality of electro-technical products. For photovoltaic applications also, the IEC standards hold true. Manufacturers need to adhere to these standards in order for their products to be saleable in the market.
Knowing now how important proper assembly is, you may want to ensure that the products you procure have been manufactured with the best possible processes.
