  1. 1. Multicomponent TiNbCrAl nitride films produced by DCMS and HiPIMS

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Grzegorz Sadowski; [2021]
    Keywords : High entropy nitrides; thin film; HiPIMS; hardness;

    Abstract : High entropy alloys (HEAs) are made of at least five principal elements in near-equimolar proportions. The vast number of possible alloys and unconventional combinations of properties are the main benefits of HEAs. Ti, Nb, Cr, Al and N were chosen in order to create a hard, corrosion resistant coating with good thermal stability. READ MORE

  2. 2. Converting Poultry Feather Waste into Bioplastics using Green Modifying Agents

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Marc Jirström; [2021]
    Keywords : polymer technology; materials science; renewable materials; Technology and Engineering;

    Abstract : Handling of problematic waste material, and the use of fossil-based and non-biodegradable plastics are two major sustainability challenges. By developing solutions that convert waste material to bioplastics, it is possible to address both these issues. READ MORE

  3. 3. Sn-Pb-mixtures for Perovskite Solar Cells

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Fanny Amanda Karolina Baumann; [2020]
    Keywords : Perovskite Solar Cells; PSC; Sn; Tin; Lead; Pb; FAPI; Renewable Energy; Compositional Engineering; Interfaces; Morphology; PL; Photoluminescence; Thin film stability; Technology and Engineering;

    Abstract : Perovskite research has quickly gone from non-existent to one of the biggest reseach areas in Photo- voltaics. There are still many questions to be solved regarding the stability, environmental impact, reproducible large area devices, efficiency and module fabrication cost of Perovskite Solar Cells, PSCs, before commercial up-scaling.

  4. 4. Stability of electron acceptor materials for organic solar cells : a work function study of C60/C70 derivatives and N2200

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Sebastian Ekhagen; [2019]
    Keywords : ;

    Abstract : Thin films of the fullerenes PC60BM and PC70BM and the non-fullerene N2200, three popular electron acceptor materials in organic photovoltaics, have been studied, using both the Kelvin probe method as well as ultraviolet photoelectron spectroscopy. With these methods the work function was measured, as well as the highest occupied molecular orbital (HOMO) onset. READ MORE

  5. 5. Effects of the interfaces in planar hybrid lead trihalide perovskite solar cells with n-type and p-type inorganic charge transport layers

    University essay from KTH/Energiteknik

    Author : Olivier Jaques Henri Fournier; [2018]
    Keywords : ;

    Abstract : Perovskite-solceller är en framväxande och lovande tunnfilmsteknik, som uppnådde hög effektivitet på en ofantlig kort tid. Den nuvarande arkitekturen i cellen, som innefattar titanoxid och Spiro-OMeTAD (en organisk förening) som laddningstransportlager (CTL), saknar stabilitet och visar hysteretiskt beteende. READ MORE
