  1. 1. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells

    University essay from Uppsala universitet/Solcellsteknik

    Author : Klara Kiselman; [2022]
    Keywords : Solar cells; ITO; indium doped tin oxide; bifacial cell; tandem cell; transparent conductive oxides;

    Abstract : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

  2. 2. The Effect of Process Parameters on Columnar-To-Equiaxed-Transition (CET) During Electron Beam-Powder Bed Fusion of Ferritic Stainless Steel

    University essay from KTH/Materialvetenskap

    Author : Doom Eleanor Ihensekhien; [2022]
    Keywords : Additive manufacturing; E-PBM; Inoculation; process parameters; TiN; CET;

    Abstract : Electron Beam Powder Bed Fusion manufacturing of components is an additive manufacturing process that is complex and has widespread advantages for aerospace and many industrial processes. It reduces costs and has a larger powder particle size requirement. READ MORE

  3. 3. Synchrotrons as a Source for Soft X-Ray Lithography

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Thomas Joseph Grandsaert Jr; [2021]
    Keywords : Physics and Astronomy;

    Abstract : To move to lower modes in extreme ultra-violet lithography (EUVL) technology (and keep up with Moore’s law), new sources of soft X-ray radiation must be developed. It is clear from previous studies that Free Electron Lasers (FELs) can easily meet the in-band power requirements at these lower wavelength modes, however detailed studies for insertion devices (undulators) as a soft X-ray lithography (SXL) source are due for a re-evaluation.

  4. 4. Work function engineering for high temperature FD-SOI transistors

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Chenxi Wang; [2021]
    Keywords : ;

    Abstract : Various applications require the MOSFETs that work at a high temperature which is ambient operating temperature higher than 125 ℃. However, the traditional bulk MOSFETs at high temperature suffers from high leakage currents and threshold voltage shift, thus the performance of the bulk MOSFETs is severely degraded. READ MORE

  5. 5. The Impact of Country-Specific Contextual Factors on the Outcome of Section 1502 of the Dodd-Frank Act Regulating Conflict Minerals in the Democratic Republic of Congo

    University essay from Lunds universitet/Institutionen för handelsrätt

    Author : Oscar Andrzej Danysz; [2021]
    Keywords : Conflict minerals; DRC; adjoining countries; 3T; 3TG; Section 1502 of the Dodd-Frank Act; armed groups; tin; tungsten; tantalum; gold; US; due diligence; supply chains; unintended consequences; mining ban; embargo; artisanal and small-scale miners; implementation; policymakers; contextual factors; social; economic; political; Law and Political Science;

    Abstract : The conflict mineral crisis has been ongoing in the DRC for nearly two decades, with armed groups and increased military presence have played on the tin, tantalum, tungsten and gold to fund a brutal war across the eastern region of the country. Recent international efforts to tackle such illicit trade in conflict minerals has focused on requiring relevant stakeholders involved in the mineral sourcing from the DRC to adhere to due diligence processes on their supply chains in an attempt to identify conflict-sourced minerals.
