1. 16. 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.

3. 17. 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

4. 18. Rapid expansion of roof mounted PV systems in commercial facilities - How can they be insured?

   Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Erik Lindén; [2023]
   Nyckelord :PV system fires; PV component failures; PV regulations; future PV regulations; PV risk assessment; PV risk evaluation; PV insurance price; Technology and Engineering;

   Sammanfattning : PV system components that are exposed to unmanageable strain can be overheated, which subsequently results in a fire ignition. Common failure factors are poor component quality, mechanical exposure due to natural phenomena and poor craftmanship. The underlying problem is that PV regulations are lacking in quality or are non-existent. LÄS MER

5. 19. Mathematical Model for Inverter Power Output in PV Parks

   Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

   Författare :Shashidhar Suragimath; [2023]
   Nyckelord :Mathematical Modelling; PV System; Energy Systems; Solar Inverter; Forecasting;

   Sammanfattning : Solar photovoltaic (PV) parks have proliferated all over the world as a result of the growing demand for electricity, and especially electricity from renewables. As these parks become larger and complex, it becomes increasingly important to develop accurate and efficient mathematical models that can be used to predict their performance and optimize their design.

7. 20. Design and implementation of an energy harvesting system in a prosthetic limb

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Ódinn K. Rúnarsson; [2023]
   Nyckelord :Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

   Sammanfattning : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. LÄS MER
