“…Chow [8] in his review concluded that the optimal design of any PVT system depends on the selected application and on the location. Dupeyrat et al [14] developed an improved lamination process that allowed to increase the generated current density of 2 mA cm À2 with respect to conventional lamination process. A prototype of PVT collector was furtherly built using a roll-bond as absorber.…”

“…The analysis of recent researches seems to state that PVT collectors with roll-bond absorber are the most suitable choice due to their higher performances. However, the experimental activity in this field is quite limited [14,16] and a comparison with traditional sheet-and-tube configuration is hardly found. As a result, strong conclusion about evident superiority of roll-bond configuration are difficult to be drawn and more data are needed for the sake of technologies comparison.…”

“…It is now also popular in cooling the flatplate and flexible PV modules [77][78][79][80][81][82][83][84]. Roll-Bond heat exchangers are manufactured using a well-established production process that foresees the construction of panels with various channel configurations by a sandwich bonding technique, using two 99.5% pure aluminium sheets, based on a rolling process and a consequent inflation process [77].…”

Thermal absorbers and their integration methods are critical to solar photovoltaic/thermal (PV/T) modules. These two elements directly influence the cooling effort of PV layers and as a result, the related electrical/ thermal/overall efficiency. This paper conducts a critical review on the essential thermal absorbers and their integration methods for the currently-available PV modules for the purpose of producing the combined PV/T modules. A brief overview of different PV/T technologies is initially summarized, including aspects of their structure, efficiencies, thermal governing expressions and their applications. Seven different types of thermal absorbers and four corresponding integration methods are subsequently discussed and summarized in terms of their advantages/disadvantages and the associated application for various PV/T modules. Compared to traditional thermal absorbers, such as sheet-and-tube structure, rectangular tunnel with or without fins/ grooves and flat-plate tube, these four types, i.e. microchannel heat pipe array/heat mat, extruded heat exchanger, roll-bond heat exchanger and cotton wick structure, are promising due to the significant enhancement in terms of efficiency, structure, weight, and cost etc. The appropriate or suitable integration method varies in different cases, i.e. the ethylene-vinyl acetate (EVA) based lamination method seems the best option for integration of PV layer with thermal absorber when compared with other conventional methods, such as direct contact, thermal adhesive and mechanical fixing. Finally, suggestions for further research topics are proposed from five aspects. The overall research results would provide useful information for the assistance of further development of solar PV/T modules with high feasibility for widespread application in energy supply even at district or city-level in the near future.

“…Alternate materials like low refractive index transparent layer and low UV absorbing encapsulating layer showed a 2 mA/cm 2 electrical output enhancement [3]. Further, the electrical efficiency of the PV module depends on the PV cell temperature, which in turn depends on the PV cell encapsulation and material properties, atmospheric parameters like solar intensity, ambient temperature and wind speed [4].…”

a b s t r a c tSolar Photovoltaic Thermal (PV/T) System is the integration of Solar Photovoltaic (PV) module and thermal system to serve the dual purpose of providing electricity and hot water/air simultaneously. But the high thermal resistance in a PV/T collector due to the thermal conductive adhesive, sheet and tube metal absorber reduces the heat transfer from the PV cells to the fluid and increases the overall cost of the system. This causes non-uniform and inefficient cooling of the PV cells. Hence, in this paper, a solar photovoltaic thermal module was developed by laminating a thin, flat copper sheet instead of Tedlar as the bottom layer. This modification is then integrated to a single water channel to make a PV/T collector. Primary energy saving efficiency of 35.32% was obtained at 0.01 kg/s mass flow rate, whereas the reference PV module attained only 20.87%. Theoretical calculations using material properties of the different layers of PV/T module and PV module showed a decrease in thermal resistance and an increase in thermal capacitance compared to the PV module. Also discussed in this paper was the positive results of few conformance tests conducted on the PV/T module according to IEC standards.
