  1. 1. Interfacial Dynamics at Surface Modified Molecular/Perovskite Solar Cells : How measurements are made to understand solar cell stability

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Benjamin Verbeek; [2023]
    Keywords : perovskite; solar cell; solar; energy; XPS; synchrotron;

    Abstract : Humanity has great energy demands, and must simultaneously combat climate change by curbing anthropogenic greenhouse gas emissions. Perovskite solar cells (PSC) provide a low-carbon energy source, at lower production costs than traditional silicon-based solar cells. PSC's suffer some issues with long-term stability. READ MORE

  3. 2. Hazaras Persecution in Afghanistan : A case study through the lens of protracted social conflicts and relative deprivation

    University essay from Linnéuniversitetet/Institutionen för statsvetenskap (ST)

    Author : Ahmad Zia Ashrafian; [2023]
    Keywords : Hazaras persecution; ethno-religious; psycho-cultural; Afghanistan; protracted social conflicts; relative deprivation; case study; Abdul Rahman; Taliban; IS-K; Pashtuns; Kafir;

    Abstract : This paper represents the root causes of Hazaras persecution in Afghanistan through ethno-religious and psycho-cultural approaches, using Protracted Social Conflicts (PSC) and Relative Deprivation (RD) frameworks. The Hazara community has been subject to persecution in variety of ways including assassinations, physical torture, enslavement, forced displacement, kidnapping, and target attacks by both state and non-state actors.

  4. 3. Elevated IgG4 is associated with higher risk for cholangitis, cirrhosis, ERCP and liver-transplantation among patients with primary sclerosing cholangitis

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Jennifer Carlsson; [2022]
    Keywords : Primary sclerosing cholangitis; liver disease; IgG;

    Abstract : Primary sclerosing cholangitis (PSC) is a rare inflammatory chronic liver disease that causes damage to the intra- and or extrahepatic bile ducts leading to cholestasis. As the disease proceeds the development of cirrhosis and eventually liver failure occurs. READ MORE

  5. 4. Perceptions of sexual violence: A discourse analysis of documents from the Peace and Security Council of the African Union 2010-2020

  6. 5. Characterization of as prepared and exposed Perovskitesolar cells by microscopic and spectroscopic techniques

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Nagaraju Gorella; [2021]
    Keywords : Perovskites; Solar Cell; SEM; AFM; c-AFM; Photoluminescence; Electroluminescence; Solar simulator.;

    Abstract : Studying the microstructural features, optical, and electrical properties of the thin-filmperovskite solar cells (PSC) is the main objective of this thesis work. All the PSCs used in thisthesis work were prepared by spin coating assisted with gas quenching process and the samplesreceived from Interuniversity Microelectronics Centre (IMEC), Belgium. READ MORE
