  2. 1. Synthesis and properties of pi-conjugated polymers for organic photovoltaics

    Author : Renee Kroon; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; organic photovoltaics; structure-property relationships; Conjugated polymers; energy level engineering;

    Abstract : Organic photovoltaics is a renewable energy technology able to solve global warming and the upcoming energy gap, issues that both originate from fossil fuel consumption. Out of all renewable energy sources, the Sun is the only source that produces enough energy to fulfill all our energy needs, now and in the future. READ MORE

  4. 2. 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

  5. 3. Molecular design, synthesis and performance evaluation of phenothiazine-based small molecules for efficient organic solar cells

    Author : Srikanth Revoju; Bertil Eliasson; Haining Tian; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic solar cell; small molecule donors; phenothiazine; power conversion efficiency; organisk kemi; Organic Chemistry;

    Abstract : Photovoltaics offers one of the most promising routes to generate electricity in a clean way. As an emerging technology in photovoltaics, organic solar cells (OSC) have attracted a great deal of attention owing to their potential low-cost, lightweight, flexibility and solution processability.

    Abstract : Resulting from the general availability of first-row transition metals, compared to their second- and third-row counterparts, photosensitizers (PSs) based on metals like iron have gained interest as candidates to enable photochemistry from solar energy, a largely underutilized energy source. Iron complexes equivalent to other metal complexes, currently being used as PS, do lack some of the advantageous properties required to challenge the established PSs. READ MORE
