  1. 11. Processing Technology for Si Based Tandem Solar Cells

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Nedim Aydinci; [2014]
    Keywords : ;

    Abstract : This project focuses on the investigation of Silicon based Tandem solar cell fabricated by using the Hydride Vapor Phase Epitaxy (HVPE). In the state-of-the-art multi-junction solar cell manufacturing epitaxial technologies are used for sub-cell formation, such as MOVPE (Metal Organic Vapour Phase Epitaxy) [1] or MBE (Molecular Beam Epitaxy) [2].

  3. 12. Development of Ni-based Ohmic contacts to InAs and InGaAs

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Eunjung Cha; [2013]
    Keywords : Ohmic contacts; Ni contacts; Ti contacts; annealing; Transmission Line Model; contact resistivity; Technology and Engineering;

    Abstract : Low specific contact resistivity (ρc) of alloyed Ni/Pd/Au and nonalloyed Ti/Pd/Au Ohmic contacts to unintentionally doped n-InAs and n+-In0.63Ga0.37As, which is a potential candidate for highly scaled HBTs and MOSFETs, is reported. READ MORE

  4. 13. Electrical characterization and modeling of SiC IC test structures

    University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Author : Giovanni Fevola; [2012]
    Keywords : ;

    Abstract : Ohmic contacts and resistor structures have been evaluated for a 4HSiC ECL technology. Sheet resistance, contact resistance, transfer length and specific contact resistivity have been measured with the linear transfer length method. READ MORE

  5. 14. Measuring the efficiency and charge carrier mobility of organic solar cells

    University essay from Institutionen för fysik

    Author : ABASI ABUDULIMU; [2012]
    Keywords : Solar cells; P3HT; PCBM; shourt circuit current; open circuit voltage; maximum power; fill factor; efficiency; charge carrier mobility; CELIV; DI-SCLC;

    Abstract : P3HT single layer, P3HT/PCBM bilayer and P3HT/PCBM inverted bilayer devices were produced by spin coating organic layers onto ITO patterned glass in air, and clamping it with an Au coated silicon wafer, as top electrode, at the end (Figure13). Normal and inverted bilayer devices were also fabricated with and without PEDOT:PSS. READ MORE
