  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.

  5. 24. On the road to sustainability : exploring transition and transport planning in Oslo, Norway

    University essay from Lunds universitet/LUCSUS

    Author : Marius Sandvoll Weschke; [2016]
    Keywords : Sustainability Science; transport planning; hypermobility; Oslo; multi level perspective; Social Sciences;

    Abstract : Achieving climate change mitigation targets requires a drastic cut in emissions from the transport sector – a huge challenge for regions where a heavily road-based mobility is already established, and where emissions have steadily increased for the past 20 years. Expectations of highly efficient, fast and ever-increasing mobility adds to the challenge. READ MORE

  6. 25. An initial study on external warning signals for Quiet Road Transport Vehicles

    University essay from Högskolan i Jönköping/JTH, Produktutveckling

    Author : Isabel Hwang; [2016]
    Keywords : Quiet Road Transport Vehicles; Acoustic Vehicle Alerting System; External warning signals; Sound quality; Product sound design; Psychoacoustics;

    Abstract : The increasing number of electric and hybrid vehicles in urban areas has shown to be beneficial in reducing both air and noise pollution. However, the lack of sound when driving at low speed has negatively affected the pedestrian safety since many rely on the vehicle sound for orientation. READ MORE
