  1. 1. Solar Energy Harvesting for Outdoor Applications

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Jonatan Andersson; Kristoffer Kjaerran; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The use of solar cells as a solution for different energy harvesting applications has seen a significant growth during the last few years. With recent advances in the power conversion efficiency and manufacturability of organic photovoltaic cells these systems can be made even cheaper and more available for consumers, opening up new ways for solar technology to be implemented into products.

    Sammanfattning : Lithium-ion (Li-Ion) batteries are widely used in various applications and are viable for automotive applications. The effective management of Li-Ion batteries in battery electric vehicles (BEV) plays a crucial role in performance and range. LÄS MER

  4. 3. Estimating Charging on a Sounding Rocket Experiment Using Plasma Simulation

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Emelie Modin; [2020]
    Nyckelord :Current Voltage Characteristics; SoundingRocket; SPIDER-1; SPIDER-2; Aurora; SPIS;

    Sammanfattning : The aim of this project is to model current volt-age characteristic curves for different plasma conditions (i.eelectron density, electron temperature, ion temperature andplasma potential) that can be found in active auroras. This isdone by simulating the charging of a FFU with a connectedLangmuir probe in the software SPIS. LÄS MER

  5. 4. Ferroelectric Gate-Stack on InAs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Pontus Littow; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Modern electronics are becoming more powerful and energy efficient for every new process generation. A key component in electronics is the transistor, which has made this trend possible. For many years the transistor has simply been scaled down.However, that is not possible any longer. LÄS MER

  7. 5. Finding a path through a crystal. Theoretical modelling of ionic conductivity.

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Fredrik Ericson; [2013]
    Nyckelord :teoretisk kemi; Chemistry;

    Sammanfattning : Ionic conductors have seen increased use over time. These are found in ion detectors, gas detectors and supercapacitors but finds special use in fuel cells and solar cells. Some ionic conductors are not only used as a conductor, but finds uses as insulators, ceramic blades or even as a diamond simulant. LÄS MER
