High Figure-of-Merit Telluride-Based Flexible Thermoelectric Films through Interfacial Modification via Millisecond Photonic-Curing for Fully Printed Thermoelectric Generators.

ABSTRACT: The thermoelectric generator (TEG) shows great promise for energy harvesting and waste heat recovery applications. Cost barriers for this technology could be overcome by using printing technologies. However, the development of thermoelectric (TE) materials that combine printability, high-efficiency, and mechanical flexibility is a serious challenge. Here, flexible (SbBi)₂ (TeSe)₃ -based screen-printed TE films exhibiting record-high figure of merits (ZT) and power factors are reported. A high power factor of 24 µW cm^-1  K^-2 (ZT_max  ≈ 1.45) for a p-type film and a power factor of 10.5 µW cm^-1  K^-2 (ZT_max  ≈ 0.75) for an n-type film are achieved. The TE inks, comprised of p-Bi_0.5 Sb_1.5
