Abstract Scope Intense pulse light (IPL) is a large-area, rapid method to sinter nanoparticles under ambient conditions and is emerging as a low-cost manufacturing technique to create functional films for various emerging applications. In this work, we present the first demonstration of IPL sintering of Bismuth Telluride based thermoelectric (TE) nanoparticles to create flexible TE films that can be used in thermoelectric generators. A detailed understanding of the microstructure and TE property evolution before and after the sintering process is obtained through experiments and modeling. The TE films fabricated by IPL sintering demonstrated a conductivity up to 4000 S/m, a 5-6 orders of magnitude increase compared with the unsintered film. Sintering models reveal that the heat generated during IPL sintering is sufficient to cause the TE nanoparticles to coalesce even under a single pulse condition. The modeling predictions of the necking growth are in good agreement with the experimentally observed sintering behavior.
