In the neutral, or undoped, form the polymers are either insulating or semiconducting. The polymers are converted to the electrically conductive, or doped, forms via oxidation or reduction which form delocalized charge carriers. The conductivity is electronic in nature and no current ion motion occurs in the solid state. 5.2 Encyclopedia of Inorganic Chemistry a) Kohaviit: TE 546/E-54 riiuli number: 303 b) Physical properties of Bismuth Aatommass: 208,98 amü.

Solar Energy Solar energy technologies use the sun's energy and light to provide heat, light, hot water, electricity, and even cooling, for homes, businesses, and industry. There are a variety of technologies that have been developed to take advantage of solar energy. These include: Photovoltaic Systems Producing electricity directly from sunlight. Solar cells convert sunlight directly into electricity. Solar cells are often used to power calculators and watches. They are made of semiconducting materials similar to those used in computer chips. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. This process of converting light (photons) to electricity (voltage) is called the photovoltaic (PV) effect. Solar cells are typically combined into modules that hold about
