Advanced nanomaterials for sustainable thermoelectric and cooling applications

Thermoelectric (TE) materials, which convert heat into electricity, are highly promising for sustainable energy conversion technologies. By achieving direct energy conversion without moving parts, and operating silently with zero harmful emissions, TE materials stand as potential constituents of environmentally friendly, sustainable energy technologies. However, their conversion efficiency is still lingering behind their traditional energy conversion counterparts. In this project, we intend to develop novel TE materials based on thin films by Molecular Beam Epitaxy (MBE) and bulk TE materials by advanced solid-state reactions. To explore the path towards optimized materials efficiency, thorough TE measurements and materials characterization are planned at HBKU and collaborative entities, where strong materials efficiency-structure correlation can be established. Furthermore, nanocomposite materials for radiative passive cooling will be developed for efficient and sustainable operation of TE technology. After intensive investigation of efficient materials, TE device prototypes will be explored to investigate their potential for energy conversion applications. Finally, the aim of this project aligns very well with the National Development Strategy of Qatar and strengthens its role as a global energy leader by contributing to new fields with zero-carbon energy.
