1. 1. 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].

3. 2. Lärresurser i genrepedagogisk undervisning – Undervisningsmaterialets roll i utvecklandet av elevers kompetens i sakprosaskrivande

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för utbildningsvetenskap; Lunds universitet/Svenska

   Författare :Saga Lindhé; [2023]
   Nyckelord :literacy; lärresurs; sakprosa; genrepedagogik; skrivinriktningar; Languages and Literatures;

   Sammanfattning : Teaching and Learning Resources in Genre Pedagogy – The Role of Teaching and Learning Materials in the Development of Students’ Non-Fiction Writing Skills The impact of genre pedagogy in a digitalised school means that the resources for teaching writing are largely made up of different types of model texts. Läromedelsutredningen (SOU 2021:70) carried out on behalf of the government highlights a tension between the physical textbook and alternative teaching and learning materials (TLM). LÄS MER

   Sammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. LÄS MER
