Abstract | Tin selenide (SnSe) is one of the most promising candidates to realize environmentally-friendly, cost-effectiveness, and high-performance thermoelectrics, derived from its outstanding electrical transport properties by appropriate band-gaps and intrinsic low lattice thermal conductivity from its anharmonic layered structure. Advanced aqueous synthesis possesses various unique advantages including convenient morphology control, exceptional high doping solubility, and distinctive vacancy engineering. Considering that there is urgent demand for a comprehensive survey on aqueous synthesis technique applied to thermoelectric SnSe, in this review, we provide a thorough overview of aqueous synthesis, characterizations, and thermoelectric performance in SnSe. We provide new insights into the aqueous synthesis-based strategies for improving the performance, including vacancy synergy, crystallization design, solubility breakthrough, and local lattice imperfection engineering, and try to build the inherent links between the aqueous synthesis-induced structural characteristics and the excellent thermoelectric performance. Besides, the significant advantages and potentials of aqueous synthesis route on fabricating SnSe-based two-dimensional thermoelectric generators, including nanorods, nanobelts, and nanosheets, are also discussed. In the end, we point out the controversy, strategy, and outlook toward future enhancement of SnSe-based thermoelectric materials. This review will guide the design of thermoelectric SnSe with high performance, and provide new perspectives as reference for other thermoelectric systems. |
