As the demand for renewable energy continues to grow, photovoltaic modules (PV) have attracted much attention as an important clean energy technology. The combination of thermoelectric generator (TEG) with photovoltaic (PV) systems offers significant benefits, such as using waste heat from PV to produce electricity, reducing the operating temperature of PV to extend its service life, and enhancing the efficiency of overall energy use. This review analyzes four main types of structural combinations: photovoltaic hybrid thermoelectric generation components (PV-TEG), split-spectrum photovoltaic hybrid thermoelectric generation components (SSPV-TEG), concentrating photovoltaic hybrid thermoelectric generation components (CPV-TEG), and photovoltaic/thermal hybrid thermoelectric generation components (PV/T-TEG) in order to obtain the latest relevant research developments. The structural design of the coupled system aims to optimize the integration of the TEG with the PV module for enhancing the heat transfer efficiency and power generation performance. The advantages of the PV/T-TEG system, which combines photovoltaic and thermoelectric conversion technologies, are likely to occupy an important position in the future solar energy market. While progress has been made in the application of TEG in PV, the challenges of efficiency, cost, and thermal management need to be overcome, and the opportunity to take advantage of developments in policy, innovation, and market demand will continue to improve performance through structural optimization.

With the advantages of high theoretical specific capacity (1166 mAh·g^-1) and low redox potential (–2.71 V), as well as be abundant in resources and low in cost, metallic Na is expected to be used as a promising candidate for the anode material in next-generation high performance secondary batteries. However, factors such as the unstable solid electrolyte interface, unpredictable dendritic growth, and substantial volume change during plating/stripping have hampered the development of sodium metal anodes. A reasonably designed artificial interfacial layer can better stabilize the sodium metal anode, which has been extensively investigated by researchers. This paper reviews the recent advances in the protection of sodium metal anodes by constructing different types of artificial interfacial layers, including inorganic, organic, and hybrid interface layers. Additionally, it discusses the issues and underlying causes associated with sodium metal anodes, and offers an outlook on their future development.

The study examines recent developments in Italy's renewable energy industry, focusing on advancements, challenges, and prospects. Using secondary data, the research analyzes Italy's progress in renewable energy adoption, particularly in wind, solar, and hydroelectric power, and its alignment with the European Union's climate targets. Italy has made significant strides in increasing its renewable energy capacity, driven by favorable government policies, financial incentives, and technological innovations. The analysis highlights key projects and investments that have contributed to Italy's renewable energy growth, as well as regulatory frameworks that have facilitated this transition. Despite these advancements, the industry faces challenges such as regulatory hurdles, grid integration issues, and public opposition to certain projects. Italy is on track to meet its renewable energy targets, yet further efforts are needed to enhance grid infrastructure, streamline permitting processes, and increase public acceptance. The study suggests that sustained government support and continued innovation are crucial for overcoming existing barriers and ensuring the long-term success of Italy's renewable energy sector. A proactive approach in addressing these challenges will be essential for Italy to fully realize its potential as a leader in renewable energy and contribute significantly to global sustainability goals

Silicon is increasingly recognized as a promising candidate for the next generation of high-capacity anodes in lithium-ion batteries. However, its substantial volumetric changes during charge and discharge cycles significantly reduce battery lifespan, which hampers its further development and practical application. Developing novel binders represents a critical strategy to overcome these challenges. PG (modified gallic acid crosslinked polyvinyl alcohol) exhibited excellent adhesion (1.28 N) and mechanical strength (89 MPa). Moreover, at a current density of 420 mA·g^-1, the PG55 (polyvinyl alcohol: modified gallic acid = 50:50 wt %) electrode maintained an impressive specific capacity of 2480 mAh·g^-1 after 100 cycles. Further increasing the current density to 840 mA·g^-1, the PG55 electrode retained a capacity of 1822 mAh·g^-1 after 200 cycles, while maintaining high coulombic efficiency throughout the cycling process. This study provides a significant reference for the ongoing evolution of binders applied for silicon anode.
