摘要
Transient photovoltage and charge extraction analyses are used to quantify the rate of nongeminate recombination loss within a pentacene/C-60 bilayer solar cell across the power-generating quadrant of the device. Employing these data, a simple model of cell function, based on field-independent generation and a charge-dependent nongeminate loss current without the use of any adjustable fitting parameters, is shown to be in good agreement with the experimental current/voltage behavior of the device both in the dark and under illumination.
