1. 6. Developing Environmentally Friendly Dye-sensitized Solar Cells

   Författare :Hanna Ellis; Gerrit Boschloo; Anders Hagfeldt; Erik Johansson; Aldo di Carlo; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dye-sensitized solar cells; dye; cobalt; triphenylamine; titanium dioxide; aqueous; PEDOT; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

   Sammanfattning : Due to climate change and its effects, alternative renewable energy sources are needed in the future human society. In the work of this thesis, the Dye-sensitized Solar Cell (DSC) has been investigated and characterized. LÄS MER

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

   Författare :Lei Zhang; Leif Hammarström; Yiying Wu; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

4. 8. Nanoparticle plasmonics for solar cell applications

   Författare :Viktoria Gusak; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; titanium dioxide.; Localized Surface Plasmon Resonance; mesoporous material; Plasmonic nanoparticle; amorphous hydrogenated Silicon; solar cell; Dye-Sensitized Solar Cell; diffusion;

   Sammanfattning : The energy demand of society increases rapidly, while the main source of today’s energy, the fossil fuels, eventually will be depleted and also poses environmental and climate hazards (though the global warming). Therefore there is a need for alternative, renewable energy sources, and solar photovoltaics (solar cells) will play an important role as one of them. LÄS MER

5. 9. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

   Författare :Daniel Hagberg; Licheng Sun; Olof Ramström; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Organic Chromophores; Dye Sensitized Solar Cells; Organic chemistry; Organisk kemi;

   Sammanfattning : This thesis is divided into four parts with organic chromophores for dye sensitized solar cells as the common feature and an introduction with general concepts of the dye sensitized solar cells. The first part of the thesis describes the development of an efficient organic chromophore for dye sensitized solar cells. LÄS MER

7. 10. Synthesis of Organic Chromophores for Dye Sensitized Solar Cells

   Författare :Daniel Hagberg; Licheng Sun; Elena Galoppini; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acceptor; chromophore; donor; dye sensitized solar cells; HOMO and LUMO energy level tuning; linker; organic dye.; Chemical engineering; Kemiteknik;

   Sammanfattning :   This thesis deals with development and synthesis of organic chromophores for dye sensitized solar cells. The chromophores are divided into three components; donor, linker and acceptor. The development of efficient organic chromophores for dye sensitized solar cells starts off with one new organic chromophore, D5. LÄS MER
