2. 1. XDSC : Excitonic Dye Solar Cells

   Author : Eva Unger; Gerrit Boschloo; Tom J. Savenije; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; hybrid solar cells; energy transfer; dye-sensitized solar cells; TiO2; small-molecular semiconductor; hole-transporting dye; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

   Abstract : Solar energy is the foremost power source of our planet. Driving photosynthesis on our planet for 3 billion years the energy stored in the form of fossil fuels also originates from the sun. Consumption of fossil fuels to generate energy is accompanied with CO2 emission which affects the earth's climate in a serious manner. READ MORE

4. 2. Design, Synthesis and Properties of Organic Sensitizers for Dye Sensitized Solar Cells

   Author : Karl Martin Karlsson; Licheng Sun; Jaejung Ko; KTH; []

   Abstract : This thesis gives a detailed description of the design and synthesis of new organic sensitizers for Dye sensitized Solar Cells (DSCs). It is divided in 7 chapters, where the first gives an introduction to the field of DSCs and the synthesis of organic sensitizers. READ MORE

5. 3. Exploring Electron Transfer Dynamics of Novel Dye Sensitized Photocathodes : Towards Solar Cells and Solar Fuels

   Author : Lei Zhang; Leif Hammarström; Yiying Wu; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electron transfer; Laser spectroscopy; Femtosecond spectroscopy; Transient absorption; NiO; DSSCs; DSSFDs; Charge separation; Solar energy conversion; Nanosecond photolysis; Photophysics; Kemi med inriktning mot kemisk fysik; Chemistry with specialization in Chemical Physics;

   Abstract : The design of dyes for NiO-based dye-sensitized solar cells (DSSCs) has drawn attention owing to their potential applications in photocatalysis and because they are indispensable for the development of tandem dye-sensitized solar cells. The understanding of the electron transfer mechanisms and dynamics is beneficial to guide further dye design and further improve the performance of photocathode in solar cells and solar fuel devices.

6. 4. Molecular Engineering of D-π-A Dyes for Dye-Sensitized Solar Cells

   Author : Erik Gabrielsson; Licheng Sun; Peter Bäuerle; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dye-sensitized solar cells; Molecular electronics; Molecular engineering; Organic synthesis; Photovoltaics; Kemi; Chemistry;

   Abstract : Dye-sensitized solar cells (DSSCs) present an interesting method for the conversion of sunlight into electricity. Unlike in other photovoltaic technologies, the difficult tasks of light absorption and charge transport are handled by two different materials in DSSCs. READ MORE

7. 5. Alternative Redox Couples for Dye-Sensitized Solar Cells

   Author : Sandra Feldt; Anders Hagfeldt; Gerrit Boschloo; Petra Cameron; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; redox mediator; triphenylamine; cobalt; ferrocene; titanium dioxide; regeneration; recombination; Physical Chemistry; Fysikalisk kemi;

   Abstract : Dye-sensitized solar cells (DSCs) convert sunlight to electricity at a low cost. In the DSC, a dye anchored to a mesoporous TiO2 semiconductor is responsible for capturing the sunlight. READ MORE
