Experimental Probes of Photogeneration in Neat Conjugated Polymers 

Dissociation of an excited singlet state in conjugated polymers is a process of particular interest because the semiconductor model postulated that the primary optically excited species is a well separated electron-hole state already. This would imply that the exciton binding energy is of the order kT only [23]. However, it was observed that the action spectrum of photoconduction in systems like poly-phenylenevinylene (PPV) and the laddertype poly-phenylene (LPPP) is flat within Si — So transition and increases steeply until the excess energy, relative to the 

The above conclusions are supported by several independent studies [30-33], In summary, they prove that conjugated polymers behave fundamentally no differently
