Improved performance of quantum dot-sensitized solar cells based on TiO2 nanoparticle/nanorod photoanodes

In this paper, a TiO2 nanoparticle/nanorod architecture electrode termed as P/R was fabricated and applied as photoanode of QDSSCs. The P/R composite architecture electrodes showed improved photovoltaic performance compared to single crystal TiO2 nanorod arrays. The champion efficiency of 4.42% has been achieved.316
