  1. 1. Extending Wireless Power Transfer Range for Self-Powered Micro Devices with mm-size Antenna

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Natachai Terawatsakul; [2023]
    Nyckelord :;

    Sammanfattning : The primary challenge in expanding the wireless power transfer range for miniaturized self-powered micro devices is the limited RF energy harvesting due to the small effective area and low gain of the mm-sized antennas used in these devices. This thesis introduces a method for extending the distance between an external energy source antenna (TX) and a micro-device antenna (RX) to more than 10 cm. LÄS MER

  3. 2. Comparison of Control Strategies for Wave Energy Converters

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Apram Rahoor; [2020]
    Nyckelord :;

    Sammanfattning : The development of wave power generation has been carried out since the 1790s. The technology involves capturing the energy of the wave using an actuation mechanism and converting it into useful work. Over the years many kinds of wave energy converters have been designed with varying rates of success. LÄS MER

  4. 3. Introduction to Perovskite Solar Cells in an Undergraduate Laboratory Exercise

    Kandidat-uppsats, Karlstads universitet

    Författare :Oscar Eklund; [2019]
    Nyckelord :;

    Sammanfattning : The course Functional Materials at Karlstad University aims for undergraduates to study some of the functional materials of the 21st century. One of the hottest topics in photovoltaic research is hybrid organic-inorganic perovskite solar cells due to their easy methods of fabrication, cheap costs and potential for high power conversion efficiencies.

  5. 4. SnOx electron selective layers for perovskite/silicon tandem solar cells using atomic layer deposition

    Master-uppsats, KTH/Energiteknik

    Författare :Lisa Anna Zafoschnig; [2018]
    Nyckelord :;

    Sammanfattning : In this work the application of ALD deposited SnOx films as electron transport layers in perovskite solar cells is analysed. Processes to fabricate homogeneous, transparent and conductive tin oxide films were developed on an Oxford Instruments FlexAL tool using a TDMASn precursor and H2O as oxidiser. LÄS MER

  7. 5. Light-trapping nanostructures in ultrathin GaAs solar cells : towards a record efficiency

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

    Författare :Romaric De Lepinau; [2016]
    Nyckelord :solar cells; photovoltaics; 3-5; III-V; Gallium Arsenide; light-trapping; resonance; nanostructure; nano-imprint; Technology and Engineering;

    Sammanfattning : Producing electrical power with photovoltaic solar panels is very attractive as the sun constitutes an inexhaustible source of clean energy. However, in order to make it a better alternative to other energy sources, its drawbacks must be addressed. LÄS MER
