  1. 1. Synthesis and Modification of Conjugated Materials for Polymer Solar Cells

    Författare :Zandra George; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; polymer interlayer; polymer solar cells; stability; conjugated polymers; fullerene derivatives;

    Sammanfattning : Polymer solar cells have emerged as a promising alternative to silicon based solar cells. One of the advantages of polymer solar cells is the possibility to use roll-to-roll techniques for large-scale device production. However, in order to fully utilize this technique, several issues need to be resolved. LÄS MER

  4. 3. Chemical Doping of Conjugated Polymers for Thermoelectric Applications

    Författare :Mariavittoria Craighero; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; mechanical properties; conjugated polymers; solid-state order; organic thermoelectrics; chemical doping;

    Sammanfattning : The ongoing development of interconnected and wearable small devices, which together make up the so-called Internet of Things, is driving a rising need for autonomous and on-site energy supplies. Heat, an abundant and often wasted energy source, can be harnessed through thermoelectric generators that can directly convert heat into electricity. LÄS MER

  5. 4. Conjugated polymers for optoelectronics

    Författare :Lars Johan Lindgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer Light-Emitting Diodes; Conjugated polymers; Polyfluorenes; Polymer Solar Cells;

    Sammanfattning : The work presented in thesis is divided into two parts; conjugated polymers for light-emitting diodes and conjugated polymers for solar cells. The main focus was on the synthesis and characterisation of the conjugated polymers, together with device preparation and characterisation. LÄS MER

  7. 5. Conjugated polymers on plasmonic metasurfaces for high contrast electronic paper in color

    Författare :Oliver Olsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; electrochromism; conjugated polymers; plasmonic electronic paper; PProDOT-Me2; reflective display;

    Sammanfattning : Electronic paper is the collective name of displays that, instead of emitting light, reflect the ambient light. These displays are known to have good readability in daylight and very low power consumption. However, there is a lack of electronic paper in color with high contrast and the ability to achieve video speed. LÄS MER
