  1. 1. Study of the vibronic mixing in chlorophylls with multidimensional spectroscopy

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ignacio Martínez Casasús; [2021]
    Nyckelord :Two-dimensional spectroscopy; Ultrafast spectroscopy; Chlorophyll a; Chlorophylls; Photosynthesis; Light harvesting; Vibronic mixing; Quantum coherence; Chemical physics; Chemistry;

    Sammanfattning : Chlorophylls comprise one of the most important families of molecules for the photosynthetic process. Chlorophyll-like molecules have been classically interpreted under the Gouterman model, being thought to feature two independent transitions, Qy(S1) and Qx(S2). LÄS MER

  2. 2. Active Infrared light power supply for indoor wireless sensor nodes

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Jialei Chen; [2020]
    Nyckelord :Energy Harvesting; IR; WSN; Photovoltaic;

    Sammanfattning : In order to expand the energy source in energy harvesting, this thesis explores the feasibility of using infrared light source as the energy source. Firstly, the thesis investigated the current energy harvesting solution and the way of using infrared light energy, and determined the use of crystalline solar panels as energy harvesters. LÄS MER

  3. 3. Fabrication and Evaluation of Sb2Te3/PVDF Hybrid Thermoelectric Films

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Bo Yu; [2020]
    Nyckelord :;

    Sammanfattning : Thermoelectric (TE) materials and devices have been extensively studied for harvesting waste heat energy. There is more interest to fabricate TE materials and devices at low cost and highly-efficient ways. LÄS MER

  4. 4. Electrical performance study of organic photovoltaics for indoor applications : with potential in Internet of Things devices

    Master-uppsats, Karlstads universitet

    Författare :August Andersson; [2020]
    Nyckelord :Indoor light harvesting; Internet of things IoT ; Organic Solar cell; Organic photovolaic;

    Sammanfattning : The evolution of the internet of things (IoT) opens the market opportunity for organic photovoltaic cells, especially for indoor applications where the lifetime of the organic cells is longer than outdoor. For example, IoT requires off-grid energy sources for many devices with low power consumption. LÄS MER

  5. 5. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Linnea Lindh; [2019]
    Nyckelord :Dye-sensitized solar cells; Grätzel cells; solar cells of the future; solar cells of tomorrow; spectroscopy; time-resolved spectroscopy; materials chemistry; materialkemi; Chemistry;

    Sammanfattning : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions. LÄS MER
