  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. Properties of epitaxial lateral overgrowth of GaAsP and GaAs grown by hydride vapor phase epitaxy

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Lakshman Srinivasan; [2020]
    Nyckelord :GaAsP; ELOG; HVPE; Photoluminescence; Raman;

    Sammanfattning : Direct heteroepitaxy of III-Vs on silicon (Si) has always been a challenge and there are various strategies to integrate these materials. This thesis deals with one such strategy known as Epitaxial lateral overgrowth (ELOG) which is extensively supported by experiments. LÄS MER

  4. 3. Properties of III-V/Si heterojunction fabricated by HVPE

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Prakhar Bhargava; [2020]
    Nyckelord :;

    Sammanfattning : Silicon is a promising material and is used for a wide range of applications in the electronics industry because of the high quality surface passivation given by the native oxide layer SiO2e. However, Si is not an ideal candidate for optoelectronic applications due to its indirect bandgap of 1. LÄS MER
