Photocurrent generation by charge-transfer absorption was detected by a highly sensitive measurement of the external quantum efficiency spectra of a range of polymer:fullerene photovoltaic devices, obtained by different preparation and annealing conditions. It was shown that the effective band gap of the blend, as obtained from the onset of the charge-transfer band, correlates with the open-circuit voltage of these devices.
