“…Some studies have shown that cell efficiency declines due to the non-uniform temperature across the cell [6][7][8][9] and that the lack of uniformity in temperature causes reverse saturation current, reducing the life of solar cell [10]. Other studies have shown that the maximum net output power was obtained by cooling under the minimum power required to drive the pump [11][12][13]. The pumping power is related to the flow rate and pressure drop [14].…”

“…More technologies, such as microfins, nano-wires, or miniature heat pipes and thermosyphons, can soon become suitable for HCPV. The integration of different technologies can lead to innovative and high-performing solutions: Hybrid schemes, such as hybridizations of jet impingement and microchannels [55,56], have shown the capability of reaching high heat-transfer coefficients and improving the temperature uniformity [57]. In particular, hybridizations of jet impingement and microchannel have been tested for HCPV applications.…”

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.

“…There are many different active and passive cooling methods to improve efficiency of PVT systems. While heat sink including thermoelectric generators, microchannel PV cell, using nanofluid, using PCM, direct liquid‐immersion cooling, thermosiphon system in a flat‐box absorber, using hybrid microchannel with nanofluid, heat sink including nanofluid could be listed as passive cooling methods; jet impingement, water spraying, using ferrofluid and magnetic field and jet array nanofluids impingement could be considered active cooling system in the literature …”

Summary In this study, the first time in the literature, natural zeolite has been employed for photovoltaic thermal (PVT) and experimentally tested as a thermal energy storage material. The main aim of the paper is to introduce natural zeolite as a heat storage material for PVT systems. The PVT systems integrated with phase change materials and natural zeolite were designed, the components of the system were explained, the thermodynamical modelling including the first and second laws was presented, the system performances were evaluated, performance parameters were investigated, energy and exergy efficiencies were determined, and economical analyses of each system were performed. Besides, all results were compared with a conventional PVT system. The average overall energy efficiency values for PVT experiments were 33% for paraffin, 37% for stearic acid, 40% for zeolite, and 32% for conventional PVT systems. The payback period of the PVT system with paraffin, zeolite, stearic acid, and conventional PVT was calculated as 10, 8, 9, and 9 years, respectively. The results show that the natural zeolite is a material with significant potential to be used for heat management in PVT for any meteorological condition.
