Abstract

Static and quasi-static concentrators present interesting characteristics for obtaining photovoltaic solar energy. In this work we study the characteristics of the crossed compound parabolic concentrator, formed by the intersection of two cyclindrical compound parabolic concentrators (CPC). Bifacial cells are used in this concentrator as a requirement for obtaining higher concentrations. Static and quasi-static concentrators see the sun as an extended source, so a simplified source model of radiance for the sky of Madrid is used. The figures of merit of a lossless concentrator are studied and the most important parameters influencing its optical behavior are discussed. We conclude that these concentrators obtain results that lead to a decrease in the cost of photovoltaic energy.

Limit of concentration under extended nonhomogeneous light sources

Journal Article Minano, J; Luque, A - Appl. Opt.; (United States)

Static photovoltaic concentrators, which see the sky as an extended distribution of radiance, are analyzed in a general way. The rules for achieving the highest energy on the cell are derived and the appropriate figures of merit are defined. It is concluded that casting increasingly high values of energy on the cell, which would be bifacial, require collecting a lower portion of the total sky energy. The corresponding figures of merit for the concentrators of the CPC family are analyzed, concluding that a better type of concentrator should be developed for photovoltaic applications.

Two dimensional compound parabolic concentrating collectors. Final report

Technical Report Henry, J; Gamble, N; Cassidy, S

Seven different compound parabolic concentrating (CPC) collector designs were tested by the ray trace method. The comparison of the collector was performed by simulating sunlight striking the designs at various angles of the sun during the course of the day. All of the CPC solar collector designs used the same type of reflective material, Kinglux reflective aluminum, which is a highly reflective surface used in solar applications. The CPC solar collector designs were subjected to a light source consisting of one helium-neon laser. The laser, to represent the effect of sunlight on the stationary CPC solar collector, was slowly movedmore »« less
Application of compound parabolic concentrators to solar photovoltaic conversion. Final report

Technical Report Cole, R; Gorski, A; Graven, R; ...

The final results of an analytical and experimental study of the application of nonimaging concentrators to solar photovoltaic conversion are presented. Two versions of the Compound Parabolic Concentrator (CPC) were considered, the Dielectric Compound Parabolic Concentrator (DCPC) in which the concentrator is filled with a dielectric material that satisfies requirements for Total Internal Reflection (TIR), and a conventional CPC in which metallic reflection is used for the mirror surfaces. Two working prototype panels were constructed and tested during the course of the program. The first was a 1.22 m by 1.22 m DCPC panel that requires only ten adjustments/year, hasmore »« less

Dielectric compound parabolic concentrating solar collector with frustrated total internal reflection absorber

Conference Hull, J

Since its introduction, the concept of nonimaging solar concentrators, as exemplified by the compound parabolic concentrator (CPC) design, has greatly enhanced the ability to collect solar energy efficiently in thermal and photovoltaic devices. When used as a primary concentrator, a CPC can provide significant concentration without the complication of a tracking mechanism and its associated maintenance problems. When used as a secondary, a CPC provides higher total concentration, or for a fixed concentration, tolerates greater tracking error in the primary.
Development of compound parabolic concentrators for solar thermal applications

Journal Article Allen, J; Levitz, N; Rabl, A; ... - Am. Soc. Mech. Eng., (Pap.); (United States)

The compound parabolic concentrator (CPC) is a non-focusing concentrator which achieves maximal concentration with minimal tracking requirements. It allows, for example, concentration values up to 10 without any diurnal tracking. The potential applications of the CPC cover space heating and cooling, process heating, solar thermal conversion, and photovoltaic power generation. Several CPC collectors for high temperature (up to 200/sup 0/C) operation have been designed and constructed. A variety of different configurations, materials, and fabrication techniques have been tried to determine the best possible design for a given application. Performance with non-selective and with selective (black-chrome) absorber coatings is compared. Onemore »« less
