Chemical changes that occur during each one of these steps render them performance determining. Particularly the purification steps, bypassed in conventional solid-state synthesis, are the cause for large discrepancies among similar solution-processed materials. In present work, the investigation focuses on a water-based surfactant free solution synthesis of SnSe, a highly relevant thermoelectric material. We show and rationalize that the number of leaching steps, purification solvent, annealing, and annealing atmosphere have significant influence on the Sn : Se ratio and impurity content in the powder. Such compositional changes that are undetectable by conventional characterization techniques lead to distinct consolidated materials with different types and concentration of defects. Additionally, the profound effect on their transport properties is demonstrated. We emphasize that understanding the chemistry and identifying key chemical species and their role throughout the process is paramount for optimizing material performance. Furthermore, we aim to demonstrate the necessity of comprehensive reporting of these steps as a standard practice to ensure material reproducibility.","lang":"eng"}],"status":"public","date_updated":"2024-05-27T07:35:41Z","quality_controlled":"1","day":"16","month":"04","title":"Unveiling crucial chemical processing parameters influencing the performance of solution-processed inorganic thermoelectric materials","_id":"17052","acknowledged_ssus":[{"_id":"EM-Fac"},{"_id":"NMR"},{"_id":"LifeSc"}],"publication_identifier":{"eissn":["1521-3773"],"issn":["1433-7851"]},"doi":"10.1002/anie.202402628","type":"journal_article","citation":{"ieee":"C.
