We have derived a closed-form analytical expression for intensity-modulated photovoltage spectroscopic (IMVS) responses of organic bulk-heterojunction (BHJ) solar cells. With the expression, we have predicted the features of the IMVS spectra, extracted physical parameters from the IMVS measurements, quantified the recombination characteristics of the BHJ devices, and compared the IMVS with the transient photovoltage responses. The analytical model has enabled the utilization of the quantitative information that is inherent in the IMVS measurements.
