Summary: Functionalization of polyfluorene-wrapped carbon nanotubes through Copper-Catalyzed Azide-Alkyne Cycloaddition (CuACC) without damaging their properties has been achieved. However, the conductivity of polyfluorene-SWNT films can be affected by the length and nature of polymer side-chains, hindering close contact between nanotubes. In this study, photocleavable side-chains were used to functionalize a polyfluorene-SWNT complex, which could be removed post-processing. Efficient cleavage of the side-chains containing an ortho-nitrobenzyl ether derivative was achieved under UV lamp exposure. The results demonstrate the potential of side-chain removal to improve device performance in SWNT-based materials.

Summary: A small organic molecule, 2-chlorothiazole-4-carboxylic acid (SN), is spin coated on a perovskite film to enhance the performance and stability of perovskite solar cells (PSCs). SN reacts with under-coordinated Pb2+ ions and I- vacancies due to the presence of sulfur and nitrogen donor atoms and -COOH groups, leading to suppressed charge recombination and passivated defects. The SN layer also effectively adjusts the energy level alignment, facilitating charge carrier separation and extraction in PSCs. Consequently, PSCs with SN modification achieve a champion PCE of 22.55% and retain 96% of their initial PCE after 500 h of storage in ambient air.

Summary: In recent years, there has been intensive research on perovskite/silicon tandem solar cells, leading to a rapid increase in their efficiencies. The most suitable subcell for tandem devices is a debatable topic, and this study summarizes three attractive silicon solar cells: passivated-emitter rear-cell (PERC), tunnel oxide passivated contact (TOPCon), and heterojunction (HJT) cells. Their structures and features are elucidated to understand their mechanism and potential for optimum performance. Furthermore, the characteristics and performance of perovskite/silicon tandem cells with these subcells are compared and discussed, with emphasis on the contribution of passivation layer and structure design on both sides. The recombination layer between the two subcells is also analyzed in depth, considering material chemistry, light absorption, and charge transport for achieving an optimized structure.

Summary: In this study, an interface engineering approach is used to address the challenges of Li dendrite propagation and interfacial incompatibility in solid-state electrolytes for Li metal batteries. By introducing an electronic rectifying interphase consisting of a p-Si/n-TiO2 junction and an external Al layer, electron infiltration into the electrolyte is effectively restrained, leading to dendrite reduction. Experimental results confirm the electronic rectifying behavior of the interphase, as well as improved interface compatibility and battery lifetime. X-ray computed tomography observation confirms the reduction of Li dendrite propagation behavior.

Summary: Due to the rapid development of perovskite solar cells (PSCs), their commercialization is not only attractive but perhaps the only choice to replace both thin film photovoltaics (PV) and conventional silicon PV. However, the poor long-term stability with scalability remains a challenge due to the sensitivity of perovskites under ambient conditions. Therefore, the perovskite interface has a dominant influence on the performances of PSCs.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
