  2. 1. Photoelectrochemical studies of dye-sensitized solar cells using organic dyes

    Author : Tannia Marinado; Anders Hagfeldt; Katoh Ryuzi; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; additive; charge recombination; coadsorbent; conduction band shift; dye-sensitized; electron lifetime; electron-transfer; organic dye; photoelectrochemical; photovoltaic; sensitizer; semiconductor; solar cell; solar cell efficiency; titanium dioxide; Physical chemistry; Fysikalisk kemi;

    Abstract : The dye-sensitized solar cell (DSC) is a promising efficient low-cost molecular photovoltaic device. One of the key components in DSCs is the dye, as it is responsible for the capture of sunlight. State-of-the-art DSC devices, based on ruthenium dyes, show record efficiencies of 10-12 %. READ MORE

  4. 2. Ionic Liquid Electrolytes for Photoelectrochemical Solar Cells

    Author : Heléne Gamstedt; Lars A. Kloo; Michael Grätzel; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ionic liquid electrolytes; Photoelectrochemical solar cells; Inorganic chemistry; Oorganisk kemi;

    Abstract : Potential electrolytes for dye-sensitized photoelectrochemical solar cells have been synthesized and their applicability has been investigated. Different experimental techniques were used in order to characterize the synthesized electrolytes, such as elemental analysis, electrospray ionisation/mass spectrometry, cyclic voltammetry, dynamic viscosity measurements, as well as impedance, Raman and NMR spectroscopy.
