Overcoming Thermal Bottlenecks in Energy Conversion Hardware with Nano-Engineered Materials and Interfaces

Thermal management in energy conversion hardware is an increasingly critical field in response to the worldwide drive for electrification and deployment of high power density technologies. Devices such as photovoltaics, power inverters, and advanced semiconductor platforms—including high electron mobility transistors (HEMTs) and metal oxide semiconductor field effect transistors (MOSFETs)—routinely face performance challenges posed by localized heat generation. These thermal issues not only limit efficiency and reduce reliability but also shorten the operational lifespan of vital components, impacting both the economic and operational sustainability of next-generation energy systems. Recent research highlights that many persistent thermal bottlenecks arise from nanoscale phenomena and interfacial resistances, rather than from the properties of bulk materials. Despite significant advances in nano-engineered materials and interfacial engineering—especially in the areas of semiconductor substrates, diamond-based heat spreaders, and advanced thermal interface materials (TIMs)—integrating these breakthroughs into scalable, manufacturable energy hardware remains a substantial challenge.This Research Topic aims to unify the nanoenergy, solar energy, and energy hardware communities to address the pressing challenge of thermal bottlenecks impeding modern energy systems. It specifically seeks to identify and illuminate how innovations at the nanoscale—including material design and interface engineering—can enhance efficiency, power density, reliability, and device lifetime. Special focus is given to power semiconductor devices like HEMTs and MOSFETs, where effective management of localized heating and interfacial resistance is paramount. Central objectives are to foster multidisciplinary insights that connect fundamental thermal transport physics, interface phenomena, and material science with system-level performance, reliability, and stability in real-world devices. The topic also aims to catalyze the systematic integration of these nano-enabled advances into practical, scalable devices and modules, with an emphasis on demonstrable improvements in hardware used for renewable and sustainable energy applications.This Research Topic is confined to innovations leveraging nano-engineered materials, interfaces, or nanoscale structuring that have clear, direct relevance to the performance and reliability of energy conversion hardware. Generic studies on electronics cooling, materials science lacking specific energy-device application, or research focused on fossil energy hardware are outside its intended scope.
