“…Recently, we propose to modify the surface of h-BN fillers with polydopamine (PDA) to improve the interfacial compatibility, and the in-plane thermal conductivity of composite films increases almost 161% from 16.6 to 26.8 W·m –1 ·K –1 . In fact, the thermal conductivity of composites strongly depends on several key parameters, such as the intrinsic thermal conductivity of the matrix and h-BN filler, − the geometric size and orientation of the h-BN filler, − and the interface. , However, a systematic and quantitative understanding of the relationship between these factors and thermal conductive properties is still lacking.…”

Understanding the relationship between the physical properties of composite components and thermal conductivity is conducive to optimize the overall heat-dissipation performance. Herein, we conduct a numerical simulation to investigate the anisotropic thermal conductivity and heat flux distributions of hexagonal boron nitride (h-BN)/nanofiber composite films. The critical issues to be considered include the effect of the intrinsic thermal conductivity of the nanofiber matrix and h-BN filler, the geometric size and orientation of the h-BN filler, and the interface thermal resistance. The results demonstrate that increasing the intrinsic thermal conductivity of nanofiber matrix is beneficial to bridge the straightforward h-BN pathway along the directional heat transfer, and the thermal barrier can be effectively inhibited by tuning the interface thermal resistance below 10 −8 m 2 •K•W −1 . As for the h-BN fillers, increasing their intrinsic thermal conductivity and length have very limited contributions to the improvement of anisotropic thermal conductivity. But raising the aspect ratio of h-BN and regulating the orientation of the well-stacked layered h-BN filler toward the heat source transfer direction are conducive to enhance the directional thermal conductivity. Based on these comprehensive mathematical analyses of all of the influencing factors, we propose an optimized equation for effectively predicting the anisotropic thermal conductivity of h-BN/nanofiber composite films. The findings are expected to guide the design of highly anisotropic thermal conductive materials.

Tin oxide (SnO2) is the most commonly used electron transport material for perovskite solar cells (PSCs). Various techniques have been applied to deposit tin dioxide, including spin-coating, chemical bath deposition, and magnetron sputtering. Among them, magnetron sputtering is one of the most mature industrial deposition techniques. However, PSCs based on magnetron-sputtered tin oxide (sp-SnO2) have a lower open-circuit voltage (V oc) and power conversion efficiency (PCE) than those prepared by the mainstream solution method. This is mainly due to the oxygen-related defects at the sp-SnO2/perovskite interface, and traditional passivation strategies usually have little effect on them. Herein, we successfully isolate the oxygen adsorption (Oads) defects located on the surface of sp-SnO2 from the perovskite layer using a PCBM double-electron transport layer. This isolation strategy effectively suppresses the Shockley-Read-Hall recombination at the sp-SnO2/perovskite interface, which results in an increase in the V oc from 0.93 to 1.15 V and an increase in PCE from 16.66 to 21.65%. To our knowledge, this is the highest PCE achieved using a magnetron-sputtered charge transport layer to date. The unencapsulated devices maintain 92% of their initial PCE after storage in air with a relative humidity of 30–50% after 750 h. We further use the solar cell capacitance simulator (1D-SCAPS) to confirm the effectiveness of the isolation strategy. This work highlights the application prospect of magnetron sputtering in the field of perovskite solar cells and provides a simple yet effective way to tackle the interfacial defect issue.
