  text: Production of thermoelectric materials from solution-processed particles involves
    the synthesis of particles, their purification and densification into pelletized
    material. 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.
