  4. 2. Characterisation of Organic Dyes for Solid State Dye-Sensitized Solar Cells

    Author : Ute Cappel; Anders Hagfeldt; Gerrit Boschloo; Udo Bach; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; energy alignment; hole conductor; injection; interface; perylene; photo-induced absorption; regeneration; spectroelectrochemistry; spiro-MeOTAD; Stark effect; titanium dioxide; Physical chemistry; Fysikalisk kemi; Physical Chemistry; Fysikalisk kemi;

    Abstract : Energy from the sun can be converted to low cost electricity using dye-sensitized solar cells (DSCs). Dye molecules adsorbed to the surface of mesoporous TiO2 absorb light and inject electrons into the semiconductor. READ MORE

  5. 3. Characterization of dye-sensitized solar cells : Components for environmentally friendly photovoltaics

    Author : Hanna Ellis; Anders Hagfeldt; Gerrit Boschloo; Erik Johansson; Maria Hahlin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; solar cells; dye-sensitized solar cells; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Abstract : As fossil fuels, the major source of energy used today, create the greenhouse gas carbon dioxide which causes global warming, alternative energy sources are necessary in the future. There is a need for different types of renewable energy sources such as hydropower, windpower, wave- power and photovoltaics since different parts of the world have different possibilities.

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

    Author : Hanna Ellis; Gerrit Boschloo; Anders Hagfeldt; Erik Johansson; Aldo di Carlo; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Enrichment and Separation of Phosphorylated Peptides on Titanium Dioxide Surfaces : Applied and Fundamental Studies

    Author : Anna I. K. Eriksson; Anders Hagfeldt; Katarina Edwards; Victor Agmo Hernández; Hubert Girault; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Posttranslational modification; Phosphorylation; Mass spectrometry; MALDI; Adsorption; QCM-D; Physical Chemistry; Fysikalisk kemi;

    Abstract : Protein phosphorylation is a very common posttranslational modification (PTM), which lately has been found to hold the keyrole in the development of many severe diseases, including cancer. Thereby, phosphoprotein analysis tools, generally based on specific enrichment of the phosphoryl group, have been a hot topic during the last decade. READ MORE
