  1. 1. Hybrid Plasmonic Devices for Optical Communication and Sensing

    Author : Xu Sun; Lech Wosinski; Laurent Vivien; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysik; Physics;

    Abstract : Hybrid plasmonic (HP) waveguides, a multi-layer waveguide structure supporting a hybrid mode of surface plasmonics and Si photonics, is a compromise way to integrate plasmonic materials into Si or SOI platforms, which can guide optical waves of sub-wavelength size, and with relative low propagation loss. In this thesis, several HP waveguides and devices are developed for the purposes of optical communications and sensing. READ MORE

  2. 2. Advanced Organic Hole Transport Materials for Solution-Processed Photovoltaic Devices

    Author : Xu Bo; Sun Licheng; Karl Leo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry;

    Abstract : Solution-processable photovoltaic devices (PVs), such as perovskite solar cells (PSCs) and solid-state dye-sensitized solar cells (sDSCs) show great potential to replace the conventional silicon-based solar cells for achieving low-cost and large-area solar electrical energy generation in the near future, due to their easy manufacture and high efficiency. Organic hole transport materials (HTMs) play important roles in both PSCs and sDSCs, and thereby can well facilitate the hole separation and transportation, for obtaining high performance solar cells.

  3. 3. Synthesis and Photoinduced Electron Transfer of Donor-Sensitizer-Acceptor Systems

    Author : Yunhua Xu; Licheng Sun; Björn Åkermark; Jean-Pierre Sauvage; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Artificial photosynthesis; Dye-sensitized solar cells; Electron donors; Dinuclear ruthenium complexes; Electron transfer; Organic chemistry; Organisk kemi;

    Abstract : Artificial systems involving water oxidation and solar cells are promising ways for the conversion of solar energy into fuels and electricity. These systems usually consist of a photosensitizer, an electron donor and / or an electron acceptor. READ MORE
