Abstract Multifunctional TiO2 powder consisting of solid microspheres/nanoparticles (NPs) was obtained in single step hydrothermal method. The insights of mesoporous solid TiO2 microspheres are observed as interconnected particles granules in the field emission scanning electron microscope (FESEM) investigation. Secondly, Ag nanoparticles (AgNPs) of spherical shaped with narrow size distribution was synthesised by reduction process and its extinction maximum at 413 nm was observed from UV–Vis analysis. Screen printed TiO2 photoanode containing plasmonic AgNPs was utilised to construct the dye sensitized solar cell (DSSC). The efficiency and optical properties of the bare and plasmonic devices were compared. Noticeable improvement in device efficiency is attributed to plasmonic properties of the incorporated AgNPs.

丝网印刷多功能 TiO2 光阳极与等离子体 Ag 纳米粒子用于染料敏化太阳能电池的性能增强

摘要 采用单步水热法制备了由固体微球/纳米颗粒（NPs）组成的多功能TiO2粉末。在场发射扫描电子显微镜 (FESEM) 研究中，介孔固体 TiO2 微球的洞察力被观察为相互连接的颗粒颗粒。其次，通过还原过程合成了具有窄尺寸分布的球形Ag纳米颗粒（AgNPs），并通过UV-Vis分析观察到其在413 nm处的消光最大值。丝网印刷的 TiO2 光阳极包含等离子体 AgNPs 用于构建染料敏化太阳能电池 (DSSC)。比较了裸器件和等离子体器件的效率和光学特性。器件效率的显着提高归因于掺入的 AgNPs 的等离子体特性。
