High-concentrator photovoltaic (HCPV) modules incorporate solar cells, optical devices, cooling mechanisms, and other elements in an assembly to provide the functions required to concentrate sunlight and obtain electricity. The variety of designs for configuring HCPV modules is introduced in this chapter. Thermal management, an important aspect to be considered in the design of these modules, is discussed, as are the possibilities and innovations for implementing cooling mechanisms. The behavior of HCPV modules is complex because of the different interdependent elements and involved processes and because of the changing operating conditions in the field. The experimental analysis of available modules has motivated progress in understanding this complex behavior. The influence of different atmospheric parameters on such behavior is analyzed in this chapter. In addition, existing models for the electrical characterization of HCPV modules are reviewed. Many of these models have been recently developed and are intended for a more accurate simulation of the behavior, for easier implementation, or for meeting specific needs of the HCPV industry. The availability of reliable models to predict the energy harvested by HCPV is important to promote this photovoltaic technology.

“…Therefore, it is important to control solar cell temperature by effectively removing the unwanted heat. Temperature effects on performance of conventional solar cells have been the subject of many reported studies [18][19][20][21][22][23][24][25][26][27]. One can distinguish two main methods of thermal management of solar cells: active cooling and passive cooling.…”

Abstract:We report results of experimental investigation of temperature rise in concentrated multi-junction photovoltaic solar cells with graphene-enhanced thermal interface materials. Graphene and few-layer graphene fillers, produced by a scalable environmentally-friendly liquid-phase exfoliation technique, were incorporated into conventional thermal interface materials. Graphene-enhanced thermal interface materials have been applied between a solar cell and heat sink to improve heat dissipation. The performance of the multi-junction solar cells has been tested using an industry-standard solar simulator under a light concentration of up to 2000 suns. It was found that the application of graphene-enhanced thermal interface materials allows one to reduce the solar cell temperature and increase the open-circuit voltage. We demonstrated that the use of graphene helps in recovering a significant amount of the power loss due to solar cell overheating. The obtained results are important for the development of new technologies for thermal management of concentrated photovoltaic solar cells.

“…To understand and enhance the heat dissipation efficiency of passive air cooling system, several studies has been reported in the literature. Natarajan et al [6] developed a two dimensional thermal model to predict the temperature of a concentrated PV module (concentration ratio Х 10) with and without passive cooling arrangements. The simulation results show that by adding additional fins, the cooling performance of aluminum plate heat sink can be increased.…”

Abstract-The major issue related to the passive air cooling technology for high concentration photovoltaic (HCPV) module is that their heat dissipation efficiencies highly rely on the ambient temperature and wind speed. It may not provide enough cooling for solar cells causing the malfunction of HCPV module under the worst case scenario, i.e., high ambient temperature and no wind condition. In this study, a novel passive air cooling device, named as Solar Enhanced Passive Air Cooling System (SEPACS), was proposed. To verify its performance advantage over conventional aluminum plate heat sink, a three dimensional model was developed in the CFD software. Numerical comparative analysis shows that the SEPACS can keep cell temperature under 75 o C when the concentration ratio reaches to 700, while solar cells cooled by conventional aluminum plate heat sink would be overheated at same concentration ratio.
