Currently, there is an intensive debate about how important is the "hot" state of the molecular exciton for the formation of free charges in the plastic photovoltaic devices.
In my talk, I will present a brief overview of this discussion. I will also show our recent (near-IR)pre-pump - (IR)pump - (IR)probe spectroscopy experiments which directly measure the rate hot-state relaxation in the organic-semiconductor blends. These results indicate that the formation of free charges probably occurs through the thermally activated hopping from the "cold" excited state, rather than from the "hot" one.
