1. An ink composition for printable thermoelectric materials, comprising:
a precursor material for a thermoelectric material,
a precursor material for an inorganic binder comprising a mixture of Cu, Se and S powder,
an organic binder, and
an organic solvent,
wherein a molar ratio of the Cu powder to a total of the Se and S powder combined is 2:1 and wherein a molar ratio of the Se powder to the S powder expressed by a formula (1-x)Se:xS is in the range of 0≤x≤0.20; and
wherein a weight ratio of the precursor material for a thermoelectric material to the precursor material for an inorganic binder expressed as [(1−y) thermoelectric material:y inorganic binder] is in a range of 0<y≤0.25.
