... Polymer-based packaging materials, such as polyethylene (PE) and polypropylene (PP), have been extensively used in several sectors because of their affordability, adaptability, and simplicity of manipulation. Nevertheless, these materials provide notable environmental obstacles, such as their inability to decompose naturally, substantial energy use during manufacturing, and restricted capacity for recycling [3,4,[6][7][8][9][10]. Polymer matrix nanocomposites provide a favorable option as they integrate nanoscale fillers, such as clay nanoparticles, carbon nanotubes, or cellulose nanocrystals, into the polymer matrix to enhance mechanical strength, barrier characteristics, and sustainability. ...

... Advocating for the adoption of cleaner technology can significantly decrease the emission of pollutants that are linked to several ailments. The lack of consideration for the socio-economic environment throughout the development of solar cooking technology has resulted in its poor use [55]. It is important to focus the price, acceptability, and usage of these technologies. ...

... Notably, in 2023, the figures reached their pinnacle, with 152 publications on phase-change materials and 100 on solar/Trombe walls. These findings underscore a heightened interest and focus within the research community on these technologies, emphasizing their significance in the field [53,54]. ...

... Moreover, in order to simultaneously improve the shortages of liquid leakage and poor thermal conductivity of PCM, biochar obtained by the carbonization treatment of biomass are considered a good supporting material. Biochar is found to have many grooves on surface and porous networks inside the structure, which absorbs PCMs to prevent from its liquid leakage [16][17][18]. Yang et al. [19] found that the carbonized logs had a stable tubular structure. And the maximum adsorption ratio for PCM is 81 wt%. ...

... For example, there are several comprehensive review articles on the design, fabrication, performance and applica-tions of carbon-enhanced organic PCM composites [115][116][117], which can provide valuable guidelines and inspiration to accelerate the development of high-performance hydrated salt composites. In particular, the classical theoretical models that predict the dependence of the effective thermal conductivity of organic PCM composites on the intrinsic thermal conductivity of carbon fillers; the shape, size, loading and distribution of carbon fillers; and the formation of connected networks can shed light on the design and construction of inorganic hydrated salt PCM composites [118,119]. ...

... Hence, the global efficiency of the concentrating photovoltaic and thermal (CPV/T) systems can be increased when electrical and thermal energies are simultaneously produced [10]. The CPV systems are more complex if compared to traditional PV systems [10] and it is not possible to have a standard configuration [11]. Several CPV systems different for optical, photovoltaic and thermal characteristics, are present in literature [12]. ...

... The stable output temperature and high heat storage density make latent heat energy storage (LHES) outweigh sensible heat energy storage (SHES) [8]. Phase change materials (PCMs) are the basis of LHES as they can absorb and release an immense quantum of heat energy which could be stored during phase transition [9,10]. It must possess a convenient phase transition temperature, excellent heat storage density, good thermal conductivity (k), lower volume transition ratio, zero corrosion, zero toxicity, zero phase separation/super-cooling degree, phenomenal match with structural materials, and finally economical too [11]. ...
