Density functional theory calculations predict that such a partial V-substitution constructively modifies the electronic structure near the bottom of the conduction band to improve the TE performance. The synthesized Ag1.97V0.03S0.55Se0.45 is found to possess a TE dimensionless figure-of-merit (ZT) of 0.71 at 350 K with maintaining its flexible nature. This ZT value is relatively high in comparison with those reported for flexible TE materials below 360 K. The increase in the ZT value is caused by the enhanced absolute value of the Seebeck coefficient with less significant variation in electrical resistivity. The high ZT value with the flexible nature naturally allows us to employ the Ag1.97V0.03S0.55Se0.45 as a component of flexible TE generators.","lang":"eng"}],"year":"2023","isi":1,"author":[{"first_name":"Kosuke","last_name":"Sato","full_name":"Sato, Kosuke"},{"id":"12d625da-9cb3-11ed-9667-af09d37d3f0a","full_name":"Singh, Saurabh","last_name":"Singh","orcid":"0000-0003-2209-5269","first_name":"Saurabh"},{"full_name":"Yamazaki, Itsuki","last_name":"Yamazaki","first_name":"Itsuki"},{"last_name":"Hirata","first_name":"Keisuke","full_name":"Hirata, Keisuke"},{"first_name":"Artoni Kevin R.","last_name":"Ang","full_name":"Ang, Artoni Kevin R."},{"last_name":"Matsunami","first_name":"Masaharu","full_name":"Matsunami, Masaharu"},{"full_name":"Takeuchi, Tsunehiro","last_name":"Takeuchi","first_name":"Tsunehiro"}],"language":[{"iso":"eng"}],"day":"01","has_accepted_license":"1","article_number":"125206","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"title":"Improvement of thermoelectric performance of flexible compound Ag2S0.55Se0.45 by means of partial V-substitution for Ag","citation":{"short":"K.
