  1. 16. Quinone-Pyrrole Dyad Based Polymers for Organic Batteries : From Design to Application

    Författare :Hao Huang; Martin Sjödin; Adolf Gogoll; Maria Strømme; Olle Inganäs; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Organic battery; conducting polymer; quinone; polypyrrole; spectroelectrochemistry; conductance;

    Sammanfattning : Organic electrode materials are finding increasing use in energy storage devices due to their attractive properties that allow building of flexible and low weight devices in an environmentally friendlier manner than traditional alternatives. Among these organic electrode materials, conducting redox polymers (CRPs), consisting of conducing polymer (CP) with covalently attached redox active pendant groups (PG), have attracted our interests.

    Författare :Chaoyang Kuang; Feng Gao; Sai Bai; Niclas Solin; Olle Inganäs; Mingjian Yuan; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Metal halide perovskite; Light-emitting diodes; Deprotonation; Interfacial reaction; Additive; Molecular interactions; Metall-halid-perovskiter; Lysdioder; Deprotonering; Gränsytegenererade reaktion; Tillsatsämnen; Molekylära interaktioner;

    Sammanfattning : Metal halide perovskites have emerged as a class of promising materials for a wide range of optoelectronic devices. Compared with traditional inorganic and organic semiconductors, perovskite materials can be easily processed via solution-based techniques at low temperatures and exhibit high photo-luminescence efficiency, outstanding colour purity, and superior charge transport properties, showing great promise for cost-effective and high-performance light-emitting diodes (LEDs).

  4. 18. Renewable and Scalable Energy Storage Materials Derived from Quinones in Biomass

    Författare :Lianlian Liu; Olle Inganäs; Niclas Solin; Daniel Brandell; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewable; scalable; quinones; energy storage;

    Sammanfattning : Currently there is an urgent need to reduce the use of fossil fuels, and efficient sustainable energy harvesters from sun and wind have been developed and are widely used for electricity generation. Storage of electrical energy is accordingly necessary to accommodate the time varying supply of wind and solar electricity. LÄS MER

  5. 19. Studying Morphology Formation and Charge Separation in Organic Solar Cells

    Författare :Yanfeng Liu; Fengling Zhang; Olle Inganäs; Jonas Bergqvist; Christoph J. Brabec; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : We are currently living in the era of automation and artificial intelligence, which requires more energy than ever before. Meanwhile, the reduction of carbon footprint is needed for keeping the environment sustainable. Exploring green energy is crucial. Solar power is one of the green energy sources. LÄS MER

  7. 20. Studies of Morphology and Charge-Transfer in Bulk-Heterojunction Polymer Solar Cells

    Författare :Zaifei Ma; Fengling Zhang; Olle Inganäs; Ludvig Edman; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The work presented in this thesis focuses on the two critical issues of bulk-heterojunction polymer solar cells: morphology of active layers and energy loss during charge transfer process at electron donor/acceptor interfaces. Both issues determine the performance of polymer solar cells through governing exciton dissociation, charge carrier recombination and free charge carrier transport. LÄS MER
