3. 17. Energy audit of a single-family house in a city in the middle of Sweden

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Daniela Valentina García Gimeno; [2023]
   Nyckelord :energy audit; building energy efficiency; building envelope; renewable sources; windows efficiency; insulation of houses in Sweden;

   Sammanfattning : The world is currently submerged in two big problems: supply energy crisis and climate change. It is clear that society has to do its best to overcome these challenges, and one effective way to mitigate their effects is by conducting an energy audit, which helps to identify the weaknesses and strengths of the buildings, enabling improvements in their thermal efficiency.

4. 18. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

   Master-uppsats, KTH/Materialvetenskap

   Författare :Mochen Li; [2023]
   Nyckelord :Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

   Sammanfattning : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. LÄS MER

5. 19. Hur kan framtidens energibehov säkerställas i asfaltbranschen? : En studie för att finna potentiella åtgärder som leder till ett minskat energibehov för ett asfaltverk, samt undersöka möjligheten att producera solel på en asfaltanläggning

   Master-uppsats, Linköpings universitet/Energisystem

   Författare :Stina Berglund; Tove Danielsen; [2023]
   Nyckelord :Asphalt plant; Energy audit; Energy efficiency; Renewable energy; Asfaltverk; Energikartläggning; Energieffektivisering; Förnybar energi;

   Sammanfattning : Ett scenario för att nå nettonollutsläpp av växthusgaser till år 2050 har tagits fram av IEA. I scenariot framgår att det krävs en ökning av energieffektivisering, samt att användning av förnybara energikällor bör öka under detta årtionde. LÄS MER

7. 20. Interfacial Dynamics at Surface Modified Molecular/Perovskite Solar Cells : How measurements are made to understand solar cell stability

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Benjamin Verbeek; [2023]
   Nyckelord :perovskite; solar cell; solar; energy; XPS; synchrotron;

   Sammanfattning : Humanity has great energy demands, and must simultaneously combat climate change by curbing anthropogenic greenhouse gas emissions. Perovskite solar cells (PSC) provide a low-carbon energy source, at lower production costs than traditional silicon-based solar cells. PSC's suffer some issues with long-term stability. LÄS MER
