Abstract

Doped films of organic small molecules are investigated with respect to their thermoelectric properties. A variety of hosts and dopants, for both n and p-doping, are compared. C₆₀ n-doped by Cr₂(hpp)₄ or o-MeO-DMBI-I are found to be the most promising material systems with a maximum of ZT_M = 0.069 at T_M = 40°C, assuming a doping-independent thermal conductivity due to phonon-based heat transport. This value is 16% of the current record reported for optimized devices employing the doped polymer PEDOT:PSS.
