This paper presents the results and conclusions of the C-rating project. The purpose of this project has been to define standard methods and criteria for testing, rating and specifying PV concentrator components and systems (C-systems). The general agreement on the capability of PV concentrator systems to reach cost competitive levels for PV energy in the mid-term suggested the requirement for ...
The article gives a brief description of solar parabolic-cylindrical installation and its main element, an optical concentrator. analysis is based on the most simplified sufficiently accurate methodology for calculating coefficient geometric concentration mirrors. cases ideal concentrator having small aperture are considered. A variant parabolic cylindrical flat receivers presented
Techniques and calculations are presented that give explicit expressions for the over-all performance of a luminescent solar concentrator (LSC) in terms of the intrinsic spectral response and quantum efficiency of its constituents. We examine the single dye (or inorganic ion) LSC with emphasis on the planar geometry. Preliminary data on the degradation of candidate LSC dyes under severe weather...
The submitted paper deals with the problems of trapping and enriching the gases and aerosols of the substances to be determined in the ambient atmosphere. Further, the paper is focused on the working principle of the miniaturized portable continuous concentrator we have designed and the possibilities of its application in air sampling and accumulation of organic and inorganic substances with wh...
Non-uniform irradiance patterns over Multi-Junction Cells gives rise to power losses, especially when considering spectral irradiance distributions over different junctions. Thermal effects on Silicone-on-Glass lenses affect spectral irradiance distributions. A new Photovoltaic Concentrator (CPV), formed by nine optical channels, each one with a Köhler configuration, has been designed to overco...
The term ‘‘non-delivery LTOT’’ is used to describe installations of newer home oxygen therapy systems where oxygen concentrator technology is used to provide both stationary and ambulatory oxygen.1 The use of non-delivery LTOT equipment obviates the need for oxygen supply companies to make repeat (and costly) home deliveries to replenish depleted gaseous or liquid oxygen contents, the majority ...
The crossed compound parabolic concentrator (CCPC) is one of the most efficient non-imaging solar concentrators used as a stationary solar concentrator or as a second stage solar concentrator. In this study, the CCPC is modified to demonstrate for the first time a new generation of solar concentrators working simultaneously as an electricity generator and thermal collector. The CCPC is designed...
SUMMARY The optical analysis of a solar concentrator is usually carried out by means of computer ray tracing, a microscopic method that provides an enormous amount of detailed information but obscures functional relationships. This paper describes a macroscopic approach that yields all the parameters needed for the optical design of line focus parabolic troughs in closed analytical form, requir...
-Even though most variations of solar concentrators have been studied or built at some time or other, an important class of concentrators has been overlooked until very recently. These novel concentrators have been called ideal because of their optical properties, and an example, the compound parabolic concentrator, is being tested at Argonne National Laboratory. Ideal concentrators differ radi...
