Multijunction III-V concentrator cells of several different types have demonstrated solar conversion efficiency over 40% since 2006, and represent the only third-generation photovoltaic technology to enter commercial power generation markets so far. The next stage of solar cell efficiency improvement, from 40% to 50%-efficient production cells, is perhaps the most important yet, since it is in ...
A Systematic Method of Interconnection Optimization for Dense-Array Concentrator Photovoltaic System
This paper presents a new systematic approach to analyze all possible array configurations in order to determine the most optimal dense-array configuration for concentrator photovoltaic (CPV) systems. The proposed method is fast, simple, reasonably accurate, and very useful as a preliminary study before constructing a dense-array CPV panel. Using measured flux distribution data, each CPV cells'...
Solar energy is a long-established technology, which has zero CO2 emissions, and provides low-cost for given area of land. The concentrator photovoltaic (CPV) been preference over the due to its high efficiency. In CPV system, most solar cell replaced with an optical concentrator. Various parabolic trough based systems have presented where concentration <300 achieved. current research, desig...
We present modeled results of the luminous and color outputs of a three-layer stack of fluorescent planar concentrators (FPCs). FPCs have the potential to provide sufficient luminous output to illuminate moderate-sized rooms for reasonably-sized collecting areas. It is of course necessary not only that the lumens be sufficient, but also that the light be sufficiently white as to be comfortable....
