    Sammanfattning : In order to reduce emissions from the building sector, which stands for than a fifth of the global energy consumption today, efficient and fossil free heating and cooling systems are of importance. This study investigates the combination of solar photovoltaic thermal collectors and ground source heat pump systems in order to regenerate energy to the ground in combination with free cooling.

  3. 3. Recycling end-of-life silicon PV panel with molten salt bath

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Liying Yu; [2023]
    Nyckelord :;

    Sammanfattning : Solar energy is recognized as a clean way to produce electricity. Solar PV's installed capacity is increasing in recent years. However, a PV panel has a 25-year lifespan on average. In actuality, 95% of the mass of PV components can be recycled. LÄS MER

  4. 4. Boendes agerande under energikrisen 2022/2023

    Kandidat-uppsats, Lunds universitet/Avdelningen för Installations- och klimatiseringslära

    Författare :Malin Antonsson; Beatrice Jihag; [2023]
    Nyckelord :Energianvändning; brukarbeteende; enkätundersökning; vädringsbeteende; Technology and Engineering;

    Sammanfattning : The building and service sector consume 40 percent of Sweden’s total energy use. Which of only single-family houses are responsible for 8 percent. The energy used in single family houses mainly goes to heating and hot water. 2020 the most common energy source for heating these buildings was electricity (Energimyndigheten 2022). LÄS MER

  5. 5. Photophysics of the polymer acceptor PF5-Y5 in organic photovoltaics : A first principles theory based study

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Anton Almén; [2022]
    Nyckelord :PF5-Y5; Non-fullerene-acceptor; NFA; polymer; fundamental; optical; gap; oxidation; reduction; exciton; binding; energy; oligomer; length; PF5-Y5; Non-fullerene-acceptor; NFA; polymer; fundamentalt; optiskt; gap; oxidation; reduktion; exciton; binding; energi; oligomerlängd;

    Sammanfattning : Non-fullerene Acceptors (NFAs) have gathered a great deal of interest for use inorganic photovoltaics (OPVs) due to recent breakthroughs in their power conversion efficiency and other advantages they offer over their Fullerene-based counterparts. In this work, a new promising non-fullerene polymer acceptor, PF5-Y5, have been studied using density functional theory and time-dependent density functional theory; and the effects that oligomer length, geometry relaxation and exchange-correlation interaction has on the exciton binding energies (the difference between optical and fundamental energy gaps) have been investigated.
