Solar technology offers great potential in terms of supplying the world’s energy needs. However, its current contribution to the world is still limited. The main factor is related to high initial cost of building the system. This paper will provide an up-to-date review of solar concentrators and their benefits to make solar technology affordable. It will also analyse on some of the existing sol...

In order to achieve competitive system costs in mass-production, it is essential that CPV concentrators incorporate sufficient manufacturing tolerances. This paper presents an advanced concentrator optic comprising a Fresnel lens and a refractive secondary element, both with broken rotational symmetry, an optic producing both the desired light concentration with high tolerance (high acceptance ...

The Sudbury Neutrino Observatory will use an array of 9500 Hamamatsu R1480 8-in. photomultiplier tubes and their associated concentrators to detect Cherenkov light. This paper describes an experimental investigation of the photomultiplier tubes and their concentrators, together with work done to model the angular and wavelength response. Good agreement is achieved. 0168~9002/96/$15.00 Copyright...

The compound parabolic concentrator is a promising technology for efficient solar irradiation exploitation at low- and medium-temperature levels. This collector type can be used in series of applications, such as cooling, desalination, industrial process heat applications. work presents novel that satisfying efficiency low cost due to the use flat glazing not an evacuated tube receiver.

Replex Plastics aims to develop a low-cost, low-concentration photovoltaic module using a metallized acrylic reflector designed for use with an inclined single-axis tracker. An asymmetric compound parabolic concentrator is developed and analyzed optimizing the many factors impacting the design, such as tracking strategy, manufacturing process, and cell size. Ray tracing is used to improve the d...

fibro-adiposis, cardiac dysfunction, and premature death. Subcellular protein fractionation and immunofluorescence showed nuclear localization of PG and PG and reduced membrane localization of PG. Coimmunoprecipitation showed reduced binding of PG but not PG to desmosome proteins DSP and DSG2. Transgene PG and PG were expressed in c-Kit :Sca1 cardiac progenitor cells (CPCs) isolated from the he...

The use of V-trough concentrators offers a simple approach to increasing the radiation incident on a solar receiver; this is particularly useful for increasing the temperature in thermal systems. However in order to accurately predict the performance of thermal systems under concentrated radiation, there is a need to understand the heat loss from them. This study experimentally shows that, for ...
