  1. 1. 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.

    Sammanfattning : Double perovskite materials exhibit alterations in magnetic order through manipulation oftheir crystal structure. Certain ultra thin metallic bilayers can create an exotic magnetic stateof confined spin textures called skyrmions. In both cases, new atomic arrangements leadto new electrical and magnetic properties. LÄS MER

  3. 3. Fabrication and Evaluation of Perovskite LaCrO3 Nanoparticles as Catalyst for Electrochemical Ammonia Synthesis

    Master-uppsats, Lunds universitet/Institutionen för Energivetenskaper

    Nyckelord :nitrogen reduction reaction; electrochemical ammonia synthesis; catalyst; perovskite; LaCrO3; fuel cell; renewable energy; Science General;

    Sammanfattning : As our way of living exploits the resources of the earth and our energy use keeps on increasing, we are now facing a climate crisis never seen before in modern time. To face these consequences and try to ease the harm we need to transform our extraction and use of energy. LÄS MER

  4. 4. Evaluating the economic viability of Perovskite – SHJ monolithically integrated photovoltaic modules

    Master-uppsats, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Marwyn Vernon; [2018]
    Nyckelord :solar energy; perovskite; economic viability; economics; LCOE; energy yield;

    Sammanfattning : In this study, the financial and economic viable of perovskite-SHJ tandem solar cells were determined using a detailed bottom-up cost model and energy-yield calculations. Attention to specific advancements in perovskite solar cell layer technology and large-scale deposition have been taken into account to create a realistic, viable commercial scale option for tandem production.

  5. 5. 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
