Light Intensity Dependence of Current Density–voltage Characteristics of an Organic Solar Cell and Dominance Switching Between Shockley-read-hall and Radiative Recombination Losses

Abstract: We investigated the variation of current density-voltage (J-V) characteristics of an organic solar cell (OSC) in the dark and at 9 different light intensities ranging from 0.01 to 1 sun of the AM1.5G spectrum. All three conventional parameters, short-circuit currents (Jsc), open-circuit voltage (Voc), and Fill factor (FF), representing OSC performance evolved systematically in response to light intensity increase. Unlike Jsc that showed quasi-linear monotonic increase, Voc and FF showed distinctive non-monoton… Show more
