“…These cooling methods can effectively reduce cell temperature by 5℃-40℃ for flatbed PV modules, and improve electrical efficiency by about 0.5%-10% (Al-Waeli et al, 2018;Hasan et al, 2010). Muneeshwaran et al investigated the cooling performance of PV modules with an air-cooling system, and results indicated that cell temperature with cooling channel was lower than that without cooling channel by 6℃-12℃ (Muneeshwaran et al, 2020). Hafz Muhammad Ali reviewed the recent advancements in PV cooling, and demonstrated the PCM cooling was a feasible solution to maintain cell temperature within stable range (Ali, 2020).…”

Traditional PV/T systems, with passive cooling channels, can not solve the problem of coupling power/heat source on the surface of PV modules, resulting in lower electrical efficiency of solar cells. The active spectrum regulation technology using nanofluids, is a promising method to absorb spectrum energy not responding to solar cells, and reduce cell temperature and improve electricity efficiency. Though many nanofluids have been selected as optical nanofluids to separate/decoupling electricity and heat from composite spectral energy, no feasible method was proposed to select proper nanofluids to match the ideal window of solar cells. Therefore, from the view of spectrum regulation, some blended Ag nanofluids were present to numerically investigate the performance of PV/T systems, using a 2D-Monte Carlo method. Results indicated that nanoparticle radius, ranging from 20nm to 60nm, drove the movement of peak absorption from 395nm to 520nm, following a linear profile. Meanwhile, increased volume concentration and optical thickness reduced spectral transmittance, leading to lower cell temperature but worse output performance. Additionally, blended Ag nanofluids, with particle radius of 20nm or 20/40nm (8:2), volume concentration of 2.5ppm and optical path of 10mm, were optimal solutions for both Si cell and GaAs cell. The electrical efficiency and merit function value of Si cells were 11.85% and 1.61 for 20nm nanofluid, 11.0% and 1.66 for 20/40nm (8:2) nanofluid, while that of GaAs cell were 9.30% and 1.92 for 20nm nanofluid, 9.03% and 2.05 for 20/40nm (8:2) nanofluid, respectively.

PV solar energy is the upcoming king of the energy source in the world, which is the fastest growing, most available, sustainable, clean, and environmentally friendly renewable energy. The essential characteristic of PV solar energy is generating the maximum power at mid-day. At the same time, the energy demand is high during the daytime. Due to this, PV solar energy replaces the conventional energy demand at peak periods. The sun is the source of PV solar energy, and it changed into electricity directly by using solar cells, which are made from semiconductor materials called silicon. Therefore, PV solar energy plays a crucial role in providing usable energy, and as well as reducing carbon dioxide emissions. However, the solar energy generation systems not achieved the desired efficiency yet, because of many unsolved problems like weather conditions, losses, materials made by and so on. The aims of this paper is to review the current literature on the improvement of the PV solar energy generation system's overall performance. First, to figure out the existing challenges, like environmental factors and natural phenomena that affect the PV solar modules efficiency. Then it presents the techniques that are used to enhance the PV solar modules overall performance. Finally, to propose the best ways and techniques to improve the PV modules efficiency and suggest to further studies.

“…In addition, emerging engineering materials (e.g., the phase change materials) have been used in most common engineering applications such as thermal energy storage and thermal comfort in modern buildings for the purpose of cost saving and eliminating the air pollution (Laraib Tariq et al 2020). Similarly, nanofluids (Ahmadlouydarab, Ebadolahzadeh, and Ali 2020;Ahmadi et al 2020) and air cooling technique (Murugan et al 2020) have been also proposed and adopted to improve the performance of buildings. Notwithstanding, an increasing number of projects in the construction industry have failed and the construction industry needs to struggle to achieve project success (Khlaifat et al 2019).…”

Adopting the Stimulus-Organism-Response paradigm, this paper investigates how relationship-related factors (asymmetric dependence and trust) and process-related factors (communication and coordination) influence project success. Data gathered from 173 respondents with electronic questionnaire were analyzed by Smart-PLS 3.0 software and PROCESS. The results demonstrate that project success is influenced by the relationship-related factors (asymmetric dependence and trust) between partners. Project-related factors, namely communication and coordination make the mechanism of project success more complicated. Moreover, the configuration of project control rights does not moderate the relationships among the relationship-related factors, process-related factors and project success. These findings contribute to the literature by showing the factors leading to project success and extend the literature in the domain of construction project management by presenting a Stimulus-Organism-Response paradigm and multiple serial meditations.
