“…Also, Phase Change Material (PCM) are proposed to PVT STC to improve the overall conversion efficiency during non-daylighting hours. Recently, a number of nano-materials and nanofluid channels proposed [27,28] that improves the cooling mechanism and achieved the electrical efficiency of PVT STC to 19% utilizing the base fluid as water and Al2O3 as nano-materials [29][30].

“…This technique achieved a Ucentre value of 0.9 Wm -2 K -1 and allowed the use of low emittance soft coatings (such as silver), which reduce radiative heat transfer between the glass panes and permits toughened glass pane for an increase of support pillar spacing that reduces conductive heat transfer. The problems with the low-temperature based indium seal are the scarcity and the cost; because of this, the low-temperature indium sealed vacuum glazing process has not yet been commercialised [30]. A recent successful construction of triple vacuum glazing, as shown in Fig.…”

A concise critique on harnessing the abundant solar thermal energy and improvement with vacuum insulation for the utilization and conversion is presented. This research implicates that the world is becoming a global solar smart city prompted by increasing daily demand of energy by the global population and land-use. Amongst all the renewable energy resources available, solar thermal energy collectors (STC) are the most copious because it is accessible in both direct and indirect modes with global solar thermal capacity in operation in 2019 was 479 GWth and annual energy yield estimated to be 389 TWh. Hybridization has been found to be the only way of improving the existing performance of (STC) such as hybrid photovoltaic thermal (PVT) with phase-change material (PCM) for energy storage and magneto-thermoelectric generators (MTEGs) and/or vacuum insulated TEG (VTEG) for waste heat energy conversion to electrical power. The concentrating solar power (CSP) technologies were also precisely studied and yet parabolic trough collector, dish sterling and solar tower are amongst the top solar thermal heat energy harvesters and its electrical power generation has also been comprehended. The modern eminence of vacuum insulation technologies on thermal comfort and sound insulation in sustainable low-carbon buildings is presented. The research implicates that there is still a scope of improving the building and construction sector and target to achieve not only zero-energy buildings (ZEB) but generating-energy buildings (GEB). A concise critique on vacuum insulated smart glazed windows is presented and the review implicates that the hybridization with PV and TEG and novelty in the constructional materials of vacuum glazing (VG) and translucent vacuum insulation panel (TVIP)

“…Jet impingement cooling, a favorable method to boost PV modules harvest, has been demonstrated by many studies [65][66][67][68]. According to the field synergy theory, a 180 degrees synergy will form between the jet direction perpendicular to the PV module and the temperature gradient direction of PV modules to achieve the optimal heat transfer effect.…”

“…However, the limited impact area limits the cooling effect of the PV module, since the heat transfer coefficient rapidly reduces with the increased distance from the jet inlet. To achieve uniform cooling, some researches have proposed multiple injection ports or arrays of jet improvement to maximize the cooling of PV modules [65,66]. Awad et al [65] proposed a novel micro jet impingement integrated with mini-channel to cool a concentrated PV system, and results indicated that cell temperatures with micro jet impingement integrated with mini-channel were 87°C, cell temperatures with only mini-channel were 104°C and cell temperatures without a heat spreader were 108.7°C respectively.…”

When converting solar energy to electricity, a big proportion of energy is not converted for electricity but for heating PV cells, resulting in increased cell temperature and reduced electrical efficiency. Many cooling technologies have been developed and used for PV modules to lower cell temperature and boost electric energy yield. However, little crucial review work was proposed to comment cooling technologies for PV modules. Therefore, this paper has provided a thorough review of the up-to-date development of existing cooling technologies for PV modules and given appropriate comments, comparisons and discussions. According to the ways or principles of cooling, existing cooling technologies have been classified as fluid medium cooling (air cooling, water cooling and nanofluids cooling), optimizing structural configuration cooling and phase change materials cooling.Potential influential factors and sub-methods were collected from the review work, and their contributions and impact have been discussed to guide future studies. Although most cooling technologies reviewed in this paper are matured, there are still problems need to be solved, such as the choice of cooling fluid and its usability for specific regions, the fouling accumulation and cleaning of enhanced heat exchangers with complex structures, the balance between cooling cost and net efficiency of PV modules, the cooling of circulating water in tropical areas and the freezing of circulating water in cold areas. To be advocated, due to efficient heat transfer and spectral filter characters, nanofluids can promote the effective matching of solar energy at both spectral and spatial scales to achieve orderly energy utilization.

Jet impingement is considered to be an effective technique to enhance the heat transfer rate, and it finds many applications in the scientific and industrial horizons. The objective of this paper is to summarize heat transfer enhancement through different jet impingement methods and provide a platform for identifying the scope for future work. This study reviews various experimental and numerical studies of jet impingement methods for thermal-hydraulic improvement of heat transfer surfaces. The jet impingement methods considered in the present work include shapes of the target surface, the jet/nozzle–target surface distance, extended jet holes, nanofluids, and the use of phase change materials (PCMs). The present work also includes both single-jet and multiple-jet impingement studies for different industrial applications.
