| Summary: | © 2015 The Authors. Published by Elsevier Ltd. Dye-sensitized solar cells based on ZnO double layer anti-reflection coating (DLARC) thin films are investigated. The ZnO DLARCs were prepared by stacking two different ZnO morphologies prepared by two different techniques including rf-magneton sputtering (rf-ZnO) and sparking technique (sp-ZnO). The device using rf-ZnO as the bottom layer and sp-ZnO (3 cycles) as the top one exhibits short circuit current density (J sc ) of 5.80 mA/cm 2 and the maximum power conversion efficiency (PCE) of 1.88%, which is higher than that of the device stacking in reverse order and the device using ZnO single layer anti-reflection coating (SLARC). The main enhancement of PCE is attributed to the reduction of light reflection at the substrate surface. This leads to the increase of J sc and the efficiency improvement of DSSCs. |
