Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>In this work, well‐ordered periodic nanogroove structures are constructed on the surfaces of indium tin oxide (ITO) substrates through a simple and cost‐effective patterning method, laser interference lithography (LIL). By using the nanopatterned ITO electrodes coated conformally with metal oxide thin films as the electron‐selective interlayer (ESL) fabricated by low‐temperature atomic layer deposition (ALD), periodically nanostructured cathode–active‐layer interfaces are formed in the inverted organic solar cells (OSCs). Compared with a planar‐ITO cathode, a nanopatterned ITO cathode with 30 nm high nanogrooves leads to considerably improved short‐circuit current and power conversion efficiency for poly(3‐hexylthiophene)/[6, 6]‐phenyl‐C61‐butyric acid methyl ester (P3HT/PCBM) based cells. The improvement in the photocurrent is caused by enhanced light absorption and improved charge‐carrier generation in the devices with nanostructured cathode–active‐layer interfaces.</p> </abstract>
