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

    University dissertation from Stockholm : KTH

    Author : Tannia Marinado; KTH.; [2009]
    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; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi 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. 4. Molecular Engineering of D-π-A Dyes for Dye-Sensitized Solar Cells

    University dissertation from Stockholm : KTH Royal Institute of Technology
