Abstract

original image

A simple nano-imprint technique is used to successfully fabricate efficient flexible bulk-heterojunction polymer solar cells based on PCDTBT/PC70BM, as reported by Alan J. Heeger and co-workers on page 1319. The flexible nano-patterned IZO anode with ordered periodic dot structures results in improved light absorption and increased interfacial contact area between the anode and polymer as well as between the polymer and cathode.
