Pillar-like nanostructures were fabricated on surface of ITO/PET directly by thermal nanoimprinting. The reflectance spectra of ITO/PET have been reduced apparently at incident angles of light in range of 10-80 degrees. Meanwhile, the contact angle of deionized (DI) water is also enhanced from 73.1 to 93.4 degrees. The absolute enhancement of short-circuit current density (J(sc)) and power conversion efficiency (PCE) for flexible perovskite solar cells are nearly 0.48-1.75 mA/cm(2) and 0.34-0.69% when tilt angles varied from 0 to 60 degrees in PCE measurement. This method is cost-effective, and can be utilized for different kinds of plastic-based solar cells. (C) 2019 Elsevier B.V. All rights reserved.
