摘要： In this study, we present a novel trilayered hierarchical TiO2 nanocomposite film with three different titania, i.e., nanoparticle (NP), submicron particle (SP), and nanotube (NT) for highly efficient dye-sensitized solar cells (DSSCs). The obtained trilayer-structured film exhibits efficient internal light trapping, fast electron transport and fluent redox diffusion. A significant improvement is achieved with a photoenergy conversion efficiency of 9.36% under AM 1.5 G simulated sunlight illumination, corresponding to a similar to 55% enhancement as compared to that with the same thickness of the NP layer alone. 出版者： Amsterdam: Elsevier 出版日期： 2012-04-01 出處： Journal of power sources, 2012-04, Vol.203, p.297-301 資源來源： Elsevier ScienceDirect Journals Complete 版權： 2015 INIST-CNRS 識別號： ISSN: 0378-7753 識別號： DOI: 10.1016/j.jpowsour.2011.11.052 識別號： CODEN: JPSODZ
