| dc.description | With an escalating global population inching toward 7.9 billion, the energy sector finds itself in a predicament as it strives to meet the soaring demands. The gradual depletion of conventional energy sources and the environmental toll they exact highlight the urgency to transition towards more sustainable alternatives. Solar energy, a bountiful and environmentally benign resource, has emerged as a frontrunner in this endeavor. Harnessing the sun’s energy has been an area of interest since the 7th century B.C., when magnifying glasses were used to concentrate the sun’s rays to make fire [1]. Today, solar energy has evolved exponentially and has been recognized as pivotal in tackling not only energy scarcity but also in combating climate change. The potential of solar energy is immense; the sunlight that reaches Earth in just 1 h is sufficient to meet global energy needs for an entire year [2]. The evolution of solar technology has been remarkable, and its significance in the contemporary energy landscape cannot be overstated. | |
| dc.description.abstract | In this study, we explored Photovoltaic-Thermoelectric (PV-TE) systems in-depth, addressing complexities in both steady-state and annual transient performance under realistic conditions. The analysis involved twelve distinct PV-TE configurations featuring diverse thermoelectric designs incorporating various semiconductors, multi-staging, non-uniform cross-sections, and material segmentation. Model 6, the PV-TE system with a multi-stage segmented rectangular design, emerged as the top performer, exhibiting a remarkable 12% increase in electric power output during peak sunlight compared to the base model, despite a marginal decrease in efficiency. Furthermore, this research delved into the potential of advanced nanofluid cooling, investigating options such as distilled water, titanium oxide, aluminum oxide, iron oxide, and graphene. The results underscores graphene nanofluid's superiority, demonstrating a significant enhancement in thermal management at an optimal flow velocity of 2 m/s. This improvement in thermal management refers to the effective heat dissipation and temperature control within the PV-TE system. This study underlines the critical role of strategic system design and component selection in optimizing the performance of PV-TE systems. By providing a comprehensive foundation for future developments in effective and sustainable energy solutions, this research contributes to advancing the understanding and implementation of PV-TE technology.
