Synergistic optimization of SnSe/SnS thermoelectrics: from material breakthroughs to device integration
Source abstract
Abstract
• This perspective critically analyzes the bottlenecks hindering SnSe/SnS thermoelectrics, focusing on the single-crystal to polycrystalline performance gap and n-p type asymmetry. • A holistic, four-pillar roadmap for synergistic optimization is proposed, encompassing advanced polycrystalline engineering, accelerated n-type development, AI-driven discovery, and device-centric integration. • The roadmap provides a strategic guide to bridge the gap between laboratory material breakthroughs and commercial thermoelectric device application.
