For instance, Kiyaee et al 17 implemented a new spectral splitting FL design for passive cooling of solar cells. Spectral splitting (SS) by removing high-energy solar photons is an efficient solution for lowering cell temperature.…”

The present work is carrying out the performance of an actively cooled Fresnel-based single-cell ultra-high concentration photovoltaic/thermal (UHCPV/T) system under concentration ratios (CR)s ranged between 500Â and 2500Â. Four cooling finned heat sink designs have been studied, that is, the in-line cylindrical pin fins (ICY), staggered cylindrical pin fins (SCY), inline conical pin fins (ICO), and staggered conical pin fins (SCO). The analysis was performed to study and optimize the maximum operating MJSC temperature, coolant flow outlet temperature, pressure drop across, and the thermal, electrical, and overall efficiency enhancement of the whole Fresnel-based UHCVP/T system. The numerical model has been first validated and then used to simulate the impact of the concentration ratio and Reynolds number on the limitations and records of each cooling finned design of the UHCPV/T. It was found that even though the aluminum-based-ICO pin fins heat sink can achieve the optimum overall efficiency of 80.20% under 2000Â and Re of 428; yet the aluminum-based ICY is the most appropriate pin-fins heat sink design for desalination purposes since it corresponds to the highest water outlet temperature of 66.16 C with a second-ranked overall efficiency of 72.5% under the same operating conditions.cooling microchannel, overall efficiency, pin-fins heat sinks, ultra-high concentration ratio | INTRODUCTIONConcentrating the incoming light on a small surface of high-efficiency multijunction solar cell (MJSC) can be seen as a bright energy source to generate more costeffective electricity.

“…This energy in form of heat is harnessed by hybrid systems such as thermal collectors [15], air cooling for water generation [16] and heat exchangers [8]. Also, from the optical modeling and the design of the encapsulation, it is possible to apply passive cooling techniques, based on the development of thin-film solar cells using solar spectrum splitting technique [17] in solar concentrators [18] which allows the elimination of high-energy solar photons in the infrared spectrum [19]. Materials in PV module must ensure the strength of solar cells and the manufacturing of the PV module with curved surfaces.…”

Currently, the use of photovoltaic solar energy has increased considerably due to the development of new materials and the ease to produce them, which has significantly reduced its acquisition costs. Most commercial photovoltaic modules have a flat geometry and are manufactured using metal reinforcement plates and glass sheets, which limits their use in irregular surfaces such as roofs and facades (BIPV) and the transportation sector (VIPV). The purpose of this study is to analyze the design implications of curved photovoltaic surfaces using composite materials. Considering operation and maintenance requirements, the most suitable reinforcement and encapsulation materials are selected based on references and experimental tests. It was found that the maximum radius of curvature that a polycrystalline silicon cell with the dimensions of a SunPower C60 model can achieve is 6.51 m for a failure probability lower than 5 %, which allows us to define the maximum curvature that this photovoltaic surface can reach. Additionally, an analytical model of the reinforcement was implemented using macromechanical models in Matlab™, which was validated by the finite element method employing the composite materials module in Ansys®. Therefore, this paper presents a detailed analysis of the shear stresses between the layers and of the deformations generated in the curved solar panel reinforcement. Finally, under the operating conditions assumed here, carbon fiber presents the best structural behavior in the reinforcement material, while epoxy resin exhibits a better performance in the encapsulation material. These results can facilitate the manufacturing of curved photovoltaic surfaces.

Solar energy is pollution‐free with less impact on the ecosystem, but it has limitations due to its intermittent nature attributed to sun availability for specific hours, resulting in less energy conservation efficiency. Similar to the purpose of carvings on the leaves to collect water, we are presenting a nanometer‐thick layer of silicon or chalcogenide with fused silica for photons enhancement in red and the blue portion of the spectrum within the solar energy reaching the earth's surface. The design is based on nanorod imprints on micrometer‐sized conventional fused silica, ensuring better absorption and transportation toward hybrid photovoltaic cells. Hybrid solar cells (comprising silicon and perovskites) are typically termed the future of solar power, but will not be discussed here. Effective area, optical power concentration, and second‐ and higher‐order dispersions can further help design and develop the photon concentrators.
