A patterned conducting IZO film with well-ordered periodic dot-structures with 50 or 200 nm deep features has been constructed by nanoimprinting technique as the anode of an organic solar cell. The use of the patterned anode leads to an increase in the short circuit current (Jsc) from 7.03 to 8.94 mA/cm2 and the power conversion efficiency (PCE) from 1.05 to 1.71% compared to the flat anode. The open circuit voltage (Voc) is also affected by nano-patterned structure. The PCE is also influenced by the aspect ratio of the pattern structure.
