  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].

    Sammanfattning : At the medical production company where this study took place, production of essential medicine used all over the world, is taking place. In a production line four different dimensions of single-chamber bags for a fat emulsion are filled and assembled, but there is a problem in the transfer process. LÄS MER

  5. 4. Monitoring Air Quality in Ångström Cleanroom Laboratory

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Linus Kanestad; Gustaf Andersson; Karl-Johan Hällgren; [2019]
    Nyckelord :Internet of things; Rasberry Pi; Radio;

    Sammanfattning : The air quality in the Ångström cleanroom was to be measured for monitoring and control purposes, with the measurements displayed on a website. To do this several sensors, micro controllers, means of communication, and ways to host the server were investigated. LÄS MER

  7. 5. Development of III-V RF Nanowire MOSFETs

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik
