In this paper ways of using compound parabolic concentrators as primary optical elements for concentrated photovoltaics are evaluated. The problems related to these classical non-imaging optical elements for photovoltaics applications have been evaluated by modelling different types of linear and point focus concentrators. Particular consideration is given to the issues of manufacturability and...

Research into solar absorption chillers despite their environmental benefits has been limited to date mainly larger systems whilst ignoring smaller building-scale units, which can significantly benefit from the use of optimally designed, low concentrating, non-imaging optical reflectors. A chiller system designed provide year-round space cooling for a typical primary health care facility in Cai...

sustainable development would be a key solution for climate change and renewable energy plays an important role in this policy. recently, according to increase of co2 emission and other relevant impacts, solar energy has been gaining more attentions from policy makers. thus, compound parabolic concentrators collectors are considered as one of the promising applications from solar thermal advant...

A Low Concentrating Photovoltaic Thermal system typically employs compound parabolic concentrator to focus sunlight and enhance the quality of both thermal electrical energy extracted. One major issues during this process is introduction non-uniform illumination on photovoltaic panels which can cause hot-spots significantly reduce reliability output from system. This be mitigated by integrating...

In this study, photocatalytic degradation of phenol by titanium dioxide (TiO2) in aqueous solution was evaluated. The UV energy of solar light was utilized by compound parabolic collectors (CPCs) technology. The effect of irradiation time, initial pH, and dosage of TiO2 were investigated. Aromatic intermediates (catechol, benzoquinone, and hydroquinone) were quantified during the reaction to st...

The solar trough concentrator is used to increase the radiation intensity on absorbers for water heating, desalination, or power generation purposes. In this study, optical performances of four concentrators, viz. parabolic (PTC), compound (CPC), surface uniform (SUC), and trapezoid (TTC), are simulated using Monte Carlo Ray Tracing method. Mathematical models concentrators first established. d...
