Summary: In this study, a broadband polarization rotator-splitter based on the lithium niobate on insulator platform was designed and experimentally demonstrated. The device showed efficient operation over a measured bandwidth of 130 nm at telecom wavelengths, with potential for even wider bandwidth according to simulation predictions. It exhibited low polarization crosstalk and high compatibility with common LNOI photonic devices, making it a potential key element in future LNOI photonic integrated circuits.

Summary: Recent progress in understanding the structure-mechanical property relationship in organic materials has opened up new opportunities in materials science. In this study, distinct thermal expansion behavior and negative thermal expansion were observed in different polymorphic forms of a pharmaceutical salt, with thermal expansion coefficients found to be inversely proportional to the elastic moduli. The correlation between structure and thermomechanical properties of polymorphs is crucial for the design and manufacture of functional crystalline materials in crystal engineering.

Summary: A study investigates the use of pressure to suppress interfacial resistance in Bi2Te3-based thermoelectric generators (TEGs). Through the establishment of a theoretical model and derivation of explicit expressions, the relationship between maximum output power, conversion efficiency, and interfacial resistivity is determined. Experimental results demonstrate that by applying suitable pressure, interfacial resistivity can be reduced and conversion efficiency can be improved, providing strong support for the fabrication of high-performance TEGs.

Summary: This study investigates the impact of entropy on the efficiency of solar cells, finding that entropy content significantly affects the efficiency limit of crystalline silicon solar cells. Thinner silicon wafers could provide optimum outdoor energy yield. Additionally, the entropy content has a smaller effect on c-Si technology compared to amorphous silicon technology. Furthermore, the study discusses the applications of considering entropy in photovoltaic device design and module tilt optimization.

Summary: This study presents a comparative analysis of the experimental results of five types of photovoltaic modules installed on fixed and solar tracking platforms. The results show that solar tracking increases the annual solar energy received by 28% and the electrical energy output of the PV platform by 29.6%. The solar conversion efficiency of the tracked PV platform is slightly higher (14.34%) compared to the fixed platform (14.17%). Among the PV modules, CIGS module exhibits the highest relative energy gain (34%), followed by CIS (30.8%), m-Si (30.6%), p-Si (27.3%), and CdTe (23.4%) modules.

Summary: Configuring a nanofluid spectrum splitter (NSS) with the thermally decoupled photovoltaic/thermal (PV/T) system is a feasible approach to achieve net-zero emissions. Results showed that higher nanoparticle concentration and NSS thickness enhance output thermal energy and solar utilization efficiency, and an optimized NSS thickness can improve thermal energy storage.
