Future Solar Cell Home
March 12th, 2012 at 11:02 amGrowing population of the world has led to unparalleled growth in global economy. The demand of electricity has also increased to power homes and companies. Electricity is something that has turn into needed for enjoying the life of 21st century. We have consumed our natural resources like fossil fuels, coal and oil for decades that are necessary to produce our own energy by using turbine generators in electrical power plants. Solar cell residence is 1 way to break this dependence.
It is important for us to understand it sooner that not only these fossil fuels are limited but the damages of drilling for and burning these fossil fuels is harming our health and the health of earth, science have deployed tactics of producing electricity that is significantly cleaner and harmless.

What is Solar Energy?
March 11th, 2012 at 3:52 amSolar energy is transmitted to the earth in portions of energy known as photons, which interact with the earth’s atmosphere and surface. It takes about 8 minutes and 20 seconds for the sun’s energy to reach the earth – this solar energy comes from within the sun itself.
The sun is one massive ball of gasses – mostly helium and hydrogen. When the hydrogen atoms combine to form helium, it generates energy. This procedure is called nuclear fusion. The sun radiates an enormous amount of energy every day, more than what folks can use.
Solar energy is captured and stored in Photovoltaic cells. Photovoltaic comes from the words Photo, meaning light and Volt, meaning electricity. Photovoltaic cells are called PV cells or solar cells for short. Solar electric cells are made up of some thing known as silicon. These cells have positive layers and negative layers, when charged with the sun an electric field are form between the positive and negative layers.

Solar Cell and Modules, Photovoltaic Effect
March 10th, 2012 at 2:21 pmSince of the unstoppable inflation in the price of electricity consumption, numerous have decided to use option energy converters such as solar cells. Solar cell is a device composed of glass laminate, semiconductor wafers and energy storage units employed to convert light energy from the sun to electrical energy. These are plates that are normally arranged in series in modules.
Solar cells convert light energy to electrical energy making use of the photovoltaic effect. In this phenomenon, the photons present in the sunlight pass via the clear glass laminate, hit the semiconductor wafers and allow electrons to move. Simply because of the unique properties of the wafers, electrons tend to move in only one direction, creating a direct present. In the method, the electricity produced can be utilized immediately and unused energy is stored in batteries.
