The understanding of the electronic properties of nanostructures is one of the most rapidly advancing areas in science. This has two major implications first, it will lead to the construction of nanocircuitiy and nanocomputers that will use considerably less power than current computers while being faster and smaller and second, it will lead to increasing efficiency and decreasing cost of photovoltaic power conversion ( solar energy ). 

Wind, solar thermal, and photovoltaic power together accounted in 1998 for only about 1% of U.S. electricity generation from renewable sources and only about 0.1% ofall electricity (DOE/EIA 1999a).

Cells made from GaAs are more costly than silicon cells, because the production process is not as well developed, and gallium and arsenic are not abundant materials. GaAs cells have been used when very high efficiency is needed regardless of cost such as required in space applications. They were also used in the Sunraycer, a photovoltaic-powered electric car, which won the Pentax World Solar Challenge race for solar-powered vehicles in 1987. It ran the 3000-km from Darwin to Adelaide, Australia at an average day time speed of 66-km per hour. The 1990 race was won by a... 

UL 1741 Underwriters Laboratory 1741 is a standard for the testing, listing and safety certification for electric inverters. This standard is for static inverters and charge controllers for use in photovoltaic power systems, but may be used for fuel cells.

Photovoltaic (PV) Module An integrated assembly of interconnected photovoltaic cells designed to deliver a selected level of working voltage and current at its output terminals, packaged for protection against environment degradation and suited for incorporation in photovoltaic power systems. 

BP reports that installed global solar photovoltaic capacity was 3,704,758 kilowatts at the end of 2005 within the IEA Photovoltaic Power System Program Member Countries. This was an increase of more than 100% over 2003. By 2006, that number had grown to 5,699,505 kilowatts.

Cathodic protection. Another way of keeping metal in a cathodic state is to connect it to an external direct current source. For smaller structures such as boats and domestic water water heaters the current is supplied by a sacrificial anode made of aluminum or zinc. For larger extended structures such as piers and buried pipelines, an external line-operated or photovoltaic power supply is commonly used. (All interstate oil piplines in the U.S. are required by law to employ cathodic protections.)...
