Described herein are non-aqueous ink compositions containing a polythiophene having a repeating unit complying with Formula (I) described below, one or more metalloid nanoparticles, and a liquid carrier having one or more organic solvents. The present disclosure also concerns the uses of such non-aqueous ink compositions, for example, in organic electronic devices. Formula (I) wherein R1 and R2 are each, independently, H, alkyl, fluoroalkyl, alkoxy, aryloxy, or -O-[Z-O]p-Re; wherein Z is an optionally halogenated hydrocarbylene group, p is equal to or greater than 1, and Re is H, alkyl, fluoroalkyl, or aryl.
