3. 2. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

   Master-uppsats, KTH/Tillämpad fysik

   Författare :Elaheh Aghajafari; [2023]
   Nyckelord :III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

   Sammanfattning : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

4. 3. Shallow Water : A comparison between hydraulic measurements and numerical models

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Dan Nilsson; [2023]
   Nyckelord :CFD; Surface Roughness; Manning coefficient; Hydropower;

   Sammanfattning : In the near future hydropower will be used to regulate intermittent energy sources, shallow water ways can then occur in close proximity to the power plants, where the bottom often consists of stones in a similar length scale as the water depth. The idea of this project, which has been initiated by Vattenfall R\&D, is to compare experimental measurements in a laboratory environment with numerical simulations with CFD, this to find a way to represent roughness structures where there is low relative submergence.

5. 4. Organiskt kol och potentiell metanproduktion i sediment från Alboránsjön

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

   Författare :Marianne Karlsson; [2022]
   Nyckelord :Alborán Sea; organic carbon; methane; modelling; Alboránsjön; organiskt kol; metan; modellering;

   Sammanfattning : Metan, en gas som är vida studerad i klimatsammanhang på grund av dess egenskaper som växthusgas och energikälla, har i denna studie fått uppmärksamhet i annan kontext i form av potentiell riskfaktor för tsunamin. I en samlad brittisk rapport från år 2009 har ett flertal studier pekat på möjliga faktorer som kan bidra till instabila sjö- och havsbottnar vilka har resulterat i undervattensskred med tsunami som följd.

7. 5. Thermoelectric measurements on InAs nanowires with a ratchet-barrier

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Fasta tillståndets fysik

   Författare :Hanna Lundström; [2022]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Efficient extraction of thermal energy from electrons at the micro- and nanoscale is a long-standing scientific goal that could enable novel types of heat engines, heat management, and solar cell applications. Semiconductor nanowires are a promising system for investigating such devices for several reasons, such as their thermoelectric properties, and the potential to be grown in heterostructures with high flexibility.
