Australia, and scaled up by BP Solar in Spain, the heterojunction with intrinsic thin layer (HIT) cells developed by Sanyo by replacing the diffused P-doped emitter with an amorphous silicon layer and the back contact cells developed by Stanford University for use in concentrator technology and now converted to a large area for flat plate use. All three use single-crystalline silicon, while the majority of screen-printed cells use multicrystalline silicon wafers. 

The WRS Infrastructure Environment, Inc. (WRS), thermal desorption unit (TDU) is an ex situ contaminant separation and concentration technology that primarily treats contaminated soil. The contaminant is vaporized from the soil, collected, condensed, and placed into drums...

For this paper, process modification for the purpose of source reduction in a plating operation will be defined as changes in equipment which lead to reduced generation of wastes. Purposely excluded are separation and concentration technologies covered elsewhere in this conference. The intent of this section is to list options, in rough order of simplicity of implementation, and provide information about each... 

With ARO, concentrations of 1,000 - 10,000 to 1 can be achieved using lower performance membranes. An ARO system can reconcentrate dilute solutions to at or near bath strength (typically a concentration of 40% to 70% is accomplished) without any evaporation or additional concentration technology.

In slurry service, UF is used primarily as a concentration technology. The UF reject stream can then be recycled back to a tank containing the concentrated slurry that can then be dewatered with a filter press. The permeate will contain little, if any, suspended solids and can be sent for metals removal treatment or to recycle/reclaim if metals have already been removed.

Hemispherical Bowl Technology - A solar energy concentrating technology that uses a linear receiver that tracks the focal area of a reflector or array of reflectors. 

Example Solar concentrating technologies such as parabolic dish, trough, and Scheffler reflectors can provide process heat for commercial and industrial applications. However, the reflectors need to retain their surface properties and not corrode. 

Research Opportunity New production methods to produce coatings that can protect the surface of reflectors for solar concentrating technologies...
