Doped films of organic small molecules are investigated with respect to theirthermoelectric properties. A variety of hosts and dopants, for both n andp-doping, are compared. C$_{60}$ n-doped by Cr$_2$(hpp)$_4$ or o-MeO-DMBI-I arefound to be the most promising material systems with a maximum of ZT$_\text{M}$= 0.069 at T$_\text{M}$ = 40{\deg}C, assuming a doping-independent thermalconductivity due to phonon-based heat transport. This value is 16% of thecurrent record reported for optimized devices employing the doped polymerPEDOT:PSS.
