title: Radical ion pair mediated triplet formation in polymer-fullerene blend films.
abstract: Efficient triplet formation is observed for films of high ionisation potential polythiophenes blended with a fullerene derivative, and assigned to formation via geminate charge recombination of bound radical ion pair states.
