    Introduction Our world has been in existence for billions of years and throughout all those years we have used the sun for basic energy needs. So why not be able to harness that energy and use it to power things like our homes or our cars? Many scientist have been developing alternate forms of energy called Green Energy. Green power is the solution to creating a cleaner, sustainable energy system. Renewable energy -- power from the sun, wind, plants, and moving water -- is a natural way to meet ...

    Assignment # 2 Expanded Definition Semiconductor The purpose of this definition is to create a better understanding of the very complex term semiconductor. This definition would be very beneficial to any individual involved or interested in the highly technical field of electrical engineering. I believe that this definition would be best suited for students enrolled in electrical engineering, because the concepts are laid out in a clear format. A semiconductor is a solid material whose ability t...

    Solar cells today are mostly made of silicon, one of the most common elements on Earth. The crystalline silicon solar cell was one of the first types to be developed and it is still the most common type in use today. They do not pollute the atmosphere and they leave behind no harmful waste products. Photovoltaic cells work effectively even in cloudy weather and unlike solar heaters, are more efficient at low temperatures. They do their job silently and there are no moving parts to wear out. It i...

    Semiconductors have an electrical resistivity that is in between those of good conductors and those of good insulators. Both silicon and germanium, which are the two basic semiconductors, have four electrons in the outermost electron sub shell. In formation of the lattice structure of the silicon or germanium, all the valence electrons are involved in the bonding, so the material should be an insulator. However, an unusually small amount of energy is needed to break one of the bonds and set an e...
