NewVen is an Oxford based company‚ which plans to sell‚ install and maintain photovoltaic cells. Photovoltaic’s is a method of generating electrical power by converting solar energy into usable current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic’s method employs solar panels on the roof or on the walls of the house‚ which are composed of a number of cells containing a photovoltaic cell. The UK is setting itself a mandatory target of ensuring that 15% of

Introduction Solar energy projects are considered to be of strategic importance to help solve the world’s energy crisis (Scheer‚ 2007). The solar energy market is comprised of two main components: the polysilicon that is used to produce photovoltaic cells and the actual production of the solar panels. Both components require a technical knowledge to produce and supply and are critical to the supply chain to increase solar energy usage. Many experts accuse the country of China

sunlight. Later‚ in 1876 William Adams along with Becquerel’s student Richard Day‚ discovered that selenium contained potential properties of converting light into electricity. The process in which light gets converted into electricity is called the photovoltaic effect. In this process the photons (or particles of light) excite the metal’s electrons to such a high energies where they become potent charge carriers. It took about

makes solar cells. In 1957‚ the AT&T telecom company used the “solar battery” for their cell phones. Hoffman Electronics created about 8 percent efficient solar cell. Thinking about investing in a solar array but concerned about the lifespan of photovoltaic cells? Consider this: the world’s oldest solar panel — a 60 year-old crystal ball-like contraption — still works. The panel was built by a British science teacher who wanted to prove the novel idea that sunlight could be converted into electricity

OUTSIDE THE SPRAWLING Frankfurt Messe‚ home of innumerable German trade fairs‚ stands the “Hammering Man”‚ a 21-metre kinetic statue that steadily raises and lowers its arm to bash a piece of metal with a hammer. Jonathan Borofsky‚ the artist who built it‚ says it is a celebration of the worker using his mind and hands to create the world we live in. That is a familiar story. But now the tools are changing in a number of remarkable ways that will transform the future of manufacturing. One of those
