  1. 1. Study of solution-based Cs0.1FA0.9Pb(I0.9Br0.1)3 perovskite deposition with scalable technology for solar cell production : Characterization of optical properties and function of the solar cell

    University essay from Uppsala universitet/Fysikalisk kemi

    Author : Tasnim Laskar; [2021]
    Keywords : ;

    Abstract : Climate change is one of the greatest challenges of the 21st century and is the reason for several environmental changes on earth. One reason behind climate change includes the rise ingreenhouse gas emissions in the atmosphere due to the burning of coal, gas and oil, i.e. fossil fuels. READ MORE

  3. 2. Film formation of mixed-halide perovskites for PSCs

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

    Author : Lina Ekstedt; [2021]
    Keywords : Mixed Halide Perovskites; Perovskite Solar Cells; Bandgap Tuning; In-situ Spectroscopy; Antisolvent; Interface Modifier.; Physics and Astronomy;

    Abstract : Over the last few years there has been a steady increase in interest in the exploration of perovskite materials within photovoltaic research. This can to a large extent be attributed to the incredible pace at which solar cells based on perovskites have improved in efficiency during the same time period. READ MORE

  4. 3. Intermediate layer contacts for tandem solar cells based on ALD SnO2

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Georgia Iona; [2021]
    Keywords : Ald; SnO2; tandem cell; solar cell; IML; intermediate layer;

    Abstract : In this project, samples with a metal/semiconductor/metal structure were fabricated and investigated with the potential application as the interconnecting layer of a tandem solar cell in mind. Degenerately doped p-Si and n-Si were used as bottom (metal like) contacts, as Si represents one of the most common materials for the bottom cell of tandem devices. READ MORE

  5. 4. 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

  6. 5. Study of leaching behavior of tin in Zinc-clinker and Mixed Oxide

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Olle Bertilsson; [2018]
    Keywords : Leaching; tin; Sn; Zn-clinker; Mixed Oxide; sulfuric acid; Zn; residue; H2SO4; Boliden;

    Abstract : Due to the increasing usage of Sn in different electronics, such as solders and in touchscreens, together with Boliden Rönnskärs increased intake of electronic waste as a secondaryraw material, a Zn-containing product called Zn-clinker has increasing amounts of Sn. TheZn-clinker is shipped to Boliden Zn-smelter in Odda, where the Zn-clinker is mixed in withcalcine (roasted concentrate) and leached in several steps. READ MORE
