Summary: In a concentrated solar power (CSP) tower plant, the co-optimization of the heliostat field and receiver subsystem is crucial for maximizing performance while ensuring safety and lifetime of the receiver. This study proposes a co-optimization method that integrates optical, thermal, and mechanical models into a system-level model for annual simulation and design optimization. The method is applied to two systems with surround fields and liquid sodium-cooled external receivers, optimizing for annual performance and Levelized Cost of Energy (LCOE). The results show that LCOE-based optimization leads to a less efficient system but with a higher capacity factor.

Summary: In this study, the thermoelectric properties of monolayer 2H-ZrI2 were systematically evaluated using first-principles calculations and semiclassical Boltzmann transport theory. The material exhibited good structural stability and experimental feasibility, with a moderate indirect bandgap of 1.07 eV and an acceptable lattice thermal conductivity of 6.69 W m(-1) K-1. A large power factor of up to 147.89 mW m(-1) K-2 could be achieved due to the conduction band valley degeneracy near the Fermi level. These findings suggest the potential application of monolayer 2H-ZrI2 in high-temperature thermoelectric devices.

Summary: In this study, the FP-LAPW technique executed in WIEN2k was used to analyze the structural, mechanical, optoelectronics, and transport characteristics of the double perovskite Rb2InSbX6 (X = Cl, Br). The investigated compounds were found to be stable based on their formation energy, tolerance factor, elastic properties, and phonon dispersion. Electronic characteristics were evaluated using PBE-GGA and mBJ potentials, with anticipated band gaps of 0.97 eV and 0.54 eV for Rb2InSbX6 (X = Cl, Br) respectively. The compounds showed ductile mechanical properties and exhibited positive values of Seebeck's coefficient, indicating their applicability in thermoelectric devices. The studied compounds demonstrated strong absorption and high power factor, making them suitable for thermoelectric and photovoltaic applications.

Summary: As the global population grows, the demand for food, energy, and water will increase significantly. However, limited land availability and competition for solar resources pose challenges to resource generation technologies. In the United States, both agriculture and solar energy production have adopted densification schemes to improve yields and energy output per unit of land. This research proposes an Agrivoltaic food and energy coproduction architecture that optimizes power generation while maintaining crop productivity by implementing ideal anti-tracking during critical growth periods. This technology offers a viable pathway for widespread solar implementation throughout the contiguous United States.
