Abstract

We have successfully increased the effi ciency of fl exible polymer solar cells with well-ordered nano-patterned IZO anode through a simple nano-imprint process based on a PCDTBT/ PC 70 BM BHJ active layer. The fl exible nano-patterned IZO anode was produced with UV-curable PUA [poly(urethane acrylate)] resin-coated fi lm on the polycarbonate (PC) substrate. The fl exible solar cells with regular nano-patterned structure exhibited improved light absorption and improved short circuit current ( J sc ). The overall power conversion effi ciency (PCE) (%) increased from 3.0% to 3.9% compared to a device without a nano-patterned substrate.
