Special Issue Information

Dear Colleagues,

In the ever-evolving landscape of materials science, the realm of nanomaterials has emerged as a transformative frontier, redefining the way we harness energy and understand the fundamental properties of matter. We are thrilled to launch a groundbreaking Special Issue that delves deep into the captivating world of “Recent Advances in Thermal, Electrical and Thermoelectric Properties of Nanomaterials”.

Over the years, nanomaterials have taken centre stage in scientific exploration and technological innovation. Their story is one of remarkable progress and scientific curiosity, dating back to the dawn of the nanoscience era. With roots in the discovery of new materials and advances in microscopy, nanomaterials have grown from an academic curiosity to a focal point in materials science, with a vast array of applications across diverse fields. This Special Issue retraces the significant milestones, charting the trajectory of nanomaterials' journey from the lab to the market.

Our primary aim with this Special Issue is to offer a comprehensive snapshot of the latest breakthroughs and innovations in the field of nanomaterials, focusing on their thermal, electrical, and thermoelectric properties. We expect contributions encompassing a wide range of topics, from the synthesis of novel nanomaterials to pioneering research on the manipulation of thermal conductivity, the enhancement of electrical conductance, and the optimization of thermoelectric efficiency.

We invite a diverse array of contributions, including original research articles, reviews, and perspective pieces. Our vision is to create a comprehensive mosaic of the field, offering a multidimensional view of nanomaterials focused on thermal management and thermoelectric applications. We are soliciting papers that address, but are not limited to, the following themes:

  • The synthesis and characterization of nanomaterials with tailored thermal properties;
  • Advances in thermal management using nanomaterials;
  • Innovations in thermoelectric materials and devices;
  • Theoretical models and simulations for predictive nanomaterial design;
  • Emerging trends and prospects in the field.

Conventional hole transport layer (HTL) Spiro-OMeTAD requires the addition of hygroscopic dopants due to its low conductivity and hole mobility, resulting in a high preparation cost and poor device stability. Cuprous thiocyanate (CuSCN) is a cost-effective alternative with a suitable energy structure and high hole mobility. However, CuSCN-based perovskite solar cells (PSCs) are affected by environmental factors, and the solvents of an HTL can potentially corrode the perovskite layer. In this study, a Co3O4/CuSCN/Co3O4 sandwich structure was proposed as an HTL for inorganic Cs2PbI2Cl2/CsPbI2.5Br0.5 PSCs to address these issues. The Co3O4 layers can serve as buffer and encapsulation layers, protecting the perovskite layer from solvent-induced corrosion and enhancing hole mobility at the interface. Based on this sandwich structure, the photovoltaic performances of the Cs2PbI2Cl2/CsPbI2.5Br0.5 PSCs are significantly improved, with the power conversion efficiency (PCE) increasing from 9.87% (without Co3O4) to 11.06%. Furthermore, the thermal stability of the devices is also significantly enhanced, retaining 80% of its initial PCE after 40 h of continuous aging at 60 °C. These results indicate that the Co3O4/CuSCN/Co3O4 sandwich structure can effectively mitigate the corrosion of the perovskite layer by solvents of an HTL and significantly improves the photovoltaic performance and thermal stability of devices.
