Abstract
We have studied the absorption spectra of charged excitations in sexithiophene thin films induced by doping and photogeneration. Absorption bands at 0.80 and 1.54 eV are attributed to spin-1/2 polarons, whereas a single absorption band at 1.1 eV is due to spinless bipolarons. Charge conjugation symmetry breaking is evident for both polarons and bipolarons.
