Abstract This research presents a preparation route in the field of printed thermoelectric materials and manufacturing thin thermoelectric sheets with a large scale of 5 cm∙5 cm out of Sb2Te3. The manufacturing technique itself consists of three steps: First the homogenization and structuring of the Sb2Te3 with a solvent which finishes with a thermoelectric ink; second is the film coating via doctor blading and the third step is the compaction of the sheets via sintering. The obtained thermoelectric sheets are about 139 μm thick and were examined with physico-chemical measurements. The maximum thermoelectric parameters of the produced sheets are a Seebeck coefficient of 117 μV/K and an electrical conductivity of 15∙104 S/m resulting in a power factor of 2097 μW/m⋅K2.

高性能刮刀热电微层

摘要 本研究提出了一种在印刷热电材料和用 Sb2Te3 制造 5 cm∙5 cm 大尺度薄热电片领域的制备路线。制造技术本身包括三个步骤：首先用溶剂对 Sb2Te3 进行均质化和结构化，最后用热电墨水完成；第二步是通过刮刀进行薄膜涂层，第三步是通过烧结压实板材。获得的热电片约 139 μm 厚，并通过物理化学测量进行检查。所生产板材的最大热电参数是塞贝克系数为 117 μV/K，电导率为 15∙104 S/m，功率因数为 2097 μW/m∙K2。
