  1. 21. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Jonatan Fast; [2017]
    Keywords : Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Abstract : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.

  3. 22. Optimization of through-silicon via structures in a fingerprint sensor package

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Gustaf Onsbring Gustafson; [2017]
    Keywords : Through-silicon via; Fingerprint sensor; Semiconductor package; Technology and Engineering;

    Abstract : The through-silicon via (TSV) is a type of vertical electrical connection that can pass through a silicon wafer or die. By using TSVs, compared to using wire bonding as interconnections in a capacitive fingerprint sensor, the capacitive strength between the sensor die and the finger can be increased. READ MORE

  4. 23. Bengtsson_Magnusson_Durability of construction solutions with fiber-reinforced polymers (FRP) in pedestrian bridges

    University essay from Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Author : David Bengtsson; Tommy Magnusson; [2016]
    Keywords : FRP; Friber-reinforced polymer; durability; environmental impact; weathering; composites; civil engineering;

    Abstract : Arbetet har genomförts i samarbete med Malmö Gatukontor med målet att samla in information om fiberförstärkta plastkompositer (fiber-reinforced polymer; FRP). FRP-kompositer kan vara ett intressant alternativ till konventionella byggnadsmaterial på grund av sina goda materialegenskaper. READ MORE

  5. 24. Development and Evaluation of Textile Actuators

    University essay from Linköpings universitet/Biosensorer och bioelektronik

    Author : Fredrik Ekman; [2016]
    Keywords : Conducting Polymer; Textile; Actuator; Soft Robotics;

    Abstract : Existing actuators in robotics are noisy, rigid and not very lifelike in their movements. There is a need for actuators in especially limb prosthetics and exoskeletons that are silent, softly moving and preferably operating on low currents. One such solution is the conducting polymers.

  6. 25. Geometrical and Electronic Structure Characterization of Conducting Hydroquinone Substituted Polypyrrole

    University essay from Uppsala universitet/Materialteori

    Author : Anton Segerkvist; [2016]
    Keywords : ;

    Abstract : The fundamental electronic and geometric structures of charged polypyrrole and a hydroquinone substituted polypyrrole, poly(pyrrol-3-ylhydroquinone), were investigated. A single electron was constrained over different sizes of the polymer chains, a polaron, with the purpose of finding the polaron size which minimizes the excitation energy. READ MORE
