Recent Advances in Solar Cooling Technologies and Energy Conversion

Dear Colleagues,

Solar cooling technologies and energy conversion have experienced significant advancements in recent years, transforming the landscape of sustainable energy utilization. In solar cooling, innovations have concentrated on enhancing the efficiency of absorption chillers. Through the refinement of materials and designs, absorption chillers have become more compact and cost-effective, expanding their usability across diverse climates. Furthermore, the integration of solar photovoltaic (PV) systems with absorption chillers has emerged as a promising strategy towards the utilization of sustainable energy. Additionally, progress in thermal energy storage technologies has facilitated the effective utilization of solar energy for cooling during periods of low solar availability, thus improving system reliability. In the realm of energy conversion, research efforts have been directed towards improving the efficiency and performance of solar thermal power plants. Concentrated solar power (CSP) technologies, including parabolic trough and solar tower systems, have benefited from advancements in thermal storage capabilities and novel heat transfer fluids. These developments have enabled CSP systems to achieve higher operating temperatures and conversion efficiencies, ensuring continuous electricity generation even after sunset. Overall, recent advancements in solar cooling technologies and energy conversion have propelled the transition towards sustainable energy systems, offering solutions to address the impacts of climate change.

This Special Issue seeks to showcase and distribute cutting-edge advancements in the theory, design, modeling, application, control, and condition monitoring of various aspects of solar cooling and energy conversion technologies. The scope for publication encompasses, but is not restricted to, the below topics:

• Enhanced absorption chillers.
• Hybrid solar PV and absorption cooling systems.
• Thermal energy storage innovations.
• Next-generation concentrated solar power (CSP).
• Advanced control and monitoring systems such as heat exchangers, absorbers, and reflectors, tailored for enhanced performance.
• Novel materials and components for enhanced performance and durability in solar cooling and energy conversion systems.
• Economic and environmental assessments.
