| Description |
In an organic bulk-heterojunction (BHJ) solar cell there is a constant electric field (Vbi − V)/d (where Vbi is the built-in voltage, V is the applied voltage and d is the sample thickness) in the active layer. Current–voltage (J–V) characteristics of an organic BHJ solar cell based on a blend of poly(3-hexylethiophene) (P3HT) and phenyl [6,6] C60 butyric acid methyl ester (PCBM) have been modelled by solving drift and diffusion equations taking into account the constant electric field. We fabricated the BHJ solar cells and measured their J–V characteristics. A comparison of the observed characteristics with theory shows excellent agreement. The diffusion component of the current dominates for V < Vbi and the current is not space charge limited.
