A Label‐Like Monolithic Organic Thermoelectric Generator Enabled by Local Inkjet Doping of Aligned Polymer Films (Adv. Energy Mater. 15/2025)

Organic Thermoelectric Generators

In article number 2404656, Martin Brinkmann, Mario Caironi, and co-workers present a method for integrating aligned organic semiconductor films (P3HT and PBTTT-⁸O) into thin, label-like thermoelectric generators (TEGs). High-temperature rubbing induces advantageous structural anisotropy while local inkjet doping patterns the films on ultrathin substrates. The TEGs exhibit exceptional normalized power densities of 0.33 and 1.04 nW cm⁻² K⁻², promising applications in healthcare and food packaging.
