A concentrator is a circuit with N inputs and M ≤ N outputs that can route any given subset of K ≤ M valid inputs to K of its M outputs. Concentrator circuits are important building blocks of many parallel algorithms. The design of optimal concentrator circuits is however a challenging task that has already been considered in many research papers. In this paper, we show how answer set programmi...

The characterisation of 85 rear-line-contacted silicon concentrator solar cells on one single wafer requires a fast, automated measurement system. In this paper an easy to use needle array measurement system is presented, which allows an automated sequential measurement of dark and light IV curves of all cells on one wafer. For acquiring IV curves under high illumination levels (up to 500 suns)...

The design specifications for a computer model that simulates the performance of multi-junction concentrator systems is described. The model will predict annual system power output as well as allowing detailed analysis of individual modules, the multi-junction cells and the component junctions themselves. Recent validation tests have shown that the model is able to reproduce experimental result...

A method for remote optical measurement of the geometry of nonimaging concentrators is presented. A concentrator installed in a solar tower was measured by observation of transmission patterns from the heliostat field, and comparison of the measured patterns to a ray tracing simulation. The actual geometry of the concentrator was derived from optimization of the match between real and simulated...

A new concentrator receiver containing a 7 mm X 7 mm 3J concentrator solar cell with a 37.4 % peak efficiency was developed. The receiver design includes a homogenizer, heat handling (epoxy lamination) technologies and a low resistance soldered connection and can be applied to various concentrator optics, including dish systems. The outdoor efficiency with a combination of a plastic Fresnel len...

This report describes a prograimiable transmission control unit which is attached to an IBM System/360 Model 67 machine operated in a timeshared environment. Called the Data Concentrator, this device provides service for AT^T teletype equipment, IBM typewriter terminal equipment, and remotely located computer equipment interconnected with serial-synchronous transmission data sets. The Data Conc...

Automatic Meter Reading (AMR) is the remote collection of consumption data from customer’s utility meters over telecommunications, radio, power line and other links. AMR provides water, electric and gas utility service companies the opportunity to streamline metering, billing and collection activities, increase operational efficiency and improve customer service. The AMR system consists of thre...

The uniformity of the radiation flux profile along the focal line of a linear parabolic concentrator is typically dependent on factors such as the mirror shape accuracy, gaps between mirrors and shading due to receiver supports. For a photovoltaic trough concentrator, small regions of low radiation flux can have a large impact on the entire system performance. Radiation flux profiles have been ...

In this paper we will discuss an innovative optical system for solar power applications in space. In this system solar radiation is collected by the concentrator array which transfers the concentrated solar radiation to the optical waveguide (OW) transmission line made of low loss optical fibers. The OW transmission line directs the solar radiation to the place of solar power utilization such a...
