A Novel Glass Vacuum Concentrator

N 80 24769 a Cellular Glass Substrate Solar Concentrator

Acurex Corporation, under contract to the Jet Propulsion Laboratory, is developing a second generation point focusing solar concentrator. The design is based on reflective gores fabricated of thin glass mirror bonded continuously to a contoured substrate of cellular glass. To date the preliminary design effort is complete and is reviewed in this presentation. The concentrator aperture and struc...

A microfluidic cell concentrator.

Cell concentration via centrifugation is a ubiquitous step in many cell culture procedures. At the macroscale, centrifugation suffers from a number of limitations, particularly when dealing with small numbers of cells (e.g., less than 50,000). On the other hand, typical microscale methods for cell concentration can affect cell physiology and bias readouts of cell behavior and function. In this ...

Concentrator Sliver® Cells for CHAPS Concentrator Systems

The Centre for Sustainable Energy Systems (CSES) at The Australian National University, with Origin Energy, has developed a novel cell fabrication process for single crystal silicon PV. The Sliver® cell fabrication process produces narrow and long cells. With some modifications to the current fabrication process it is possible to produce Sliver® cells suitable for concentrator systems with low ...

Novel accelerated testing method for III-V concentrator solar cells

Accelerated testing is a necessary tool in order to demonstrate the reliability of concentration photovoltaic solar cells, devices which is expected to be working not less than 25 years. Many problems arise when implementing high temperature accelerated testing in this kind of solar cells, because the high light irradiation level, at which they work, is very difficult to achieve inside a climat...
