Abstract

Aligned one-dimensional nanostructure-based solar cells have lower-performance than traditional dye-sensitized solar cells (DSSC); due to optical and electrical losses. In this letter, we minimized optical/electrical-loss by using low-temperature solution-processed ZnO nanowires (NW) as anti-reflection(AR)/electron-transport(ET) layer in newly designed indoline dye based-DSSCs. AR-layered organic-DSSC exhibit better durability performance and enhanced photocurrent density (Jsc), >26% compared to the bare devices; due to the enhanced light-coupling. Additionally, this letter debates the techniques to increase performance of the DSSCs in terms of current and voltage in detail. Such AR/ET layered architecture will be of broad academic and industrial interest, for example in photodetectors and so on.
