A comparison of performance of flat and bent photovoltaic luminescent solar concentrators
To employ new solar photovoltaic technologies in products and buildings, many systems need to be adapted. Inspired by the cylindrical shape, in this work we have evaluated the performance of luminescent solar concentrator photovoltaic (LSC-PV) elements with narrow PV cell strips that could be integrated in an outdoor lighting pole. Silicon photovoltaic (PV) cells were attached to the back of bo...
متن کاملAnalysis of the Radiation Flux Profile along a Pv Trough Concentrator
The primary advantage of a PV concentrator is that concentrating light allows a significant reduction in the area of solar cell coverage, the main cost driver in a flat plate system. PV systems, whether flat plate or concentrating, normally have groups of solar cells connected in series in order to increase voltage and limit current. However, low illumination on a single cell proportionally red...
متن کاملAnalysis of the Radiation Flux Profile of the 100 Sun Promoteo Facetted Dish Concentrator
All PV systems have cells or groups of cells connected in series in order to build up voltage and minimise current. Because current is almost linearly dependent on the incident light, the current in a string of identical solar cells will be limited by the cell with the least illumination. It is therefore important to achieve a flux profile as uniform as possible. Typically for dish concentrator...
متن کاملResults and Conclusion of C-rating Project: an European Initiative for Normalisation and Rating of Pv Concentrator Systems
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 ...
متن کاملMp Title: the Growth of Solar Concentrator Photovoltaic Markets in the Southwest Us
Worldwide solar photovoltaic (PV) markets have grown at an average rate at 38% over the past ten years. While polysilicon flat panel PV modules have traditionally dominated the overall solar market, a range of different solar energy conversion technologies are starting to gain market share. One such class of solar technologies, concentrator photovoltaics (CPV), is in its commercial infancy but ...
