  1. 1. Thin Indium Tin Oxide Layer Development for Crystalline Silicon/Perovskite Two Terminal Tandem Solar Cell

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Aravind Srinivasachari; [2023]
    Keywords : Indium Tin Oxide; Thin-film characterisation; Magnetron Sputtering; Screen printing; Tandem Solar Cells; Indium-tennoxid; karaktärisering av tunnfilm; magnetronförstoftning; screentryck; tandemsolceller;

    Abstract : ITO is widely regarded as the optimal TCO for serving as front window layer in PSK/c-Si tandem solar cells. It is known to effectively mitigate several stability issues present in perovskite solar cells while demonstrating excellent lateral conductivities and optical transparency across the entire solar spectrum.

  3. 2. Operando detection of Li-plating by online gas analysis and acoustic emission monitoring

    University essay from Uppsala universitet/Strukturkemi

    Author : Inti Espinoza Ramos; [2023]
    Keywords : Li-ion batteries; graphite; solid electrolyte interphase; lithium plating; online gas analysis; operando acoustic emission monitoring;

    Abstract : Lithium ion batteries (LIBs) are widely used for storing and converting chemical energy into electrical energy. During battery operation, lithium ions move between electrode materials, enabling energy storage. However, aging mechanisms like lithium plating can negatively impact battery performance and lifetime. READ MORE

  4. 3. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

    University essay from Uppsala universitet/Oorganisk kemi

    Author : Elina Elvelo; [2023]
    Keywords : alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

    Abstract : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

  5. 4. Extraction Replicas of Common Engineering Alloys for Analysis of Small Precipitates

    University essay from KTH/Materialvetenskap

    Author : Monika Rolinska; [2020]
    Keywords : Extraction replica; transmission electron microscopy; materials characterization; precipitation; Extraktionsrepliker; transmissionselektronmikroskopi; materialkaraktarisering; utskiljningar;

    Abstract : Characterization of small precipitates is important for development of new alloys. One inherent  difficulty  in  characterisation  of  small  precipitates  with  electron microscopy techniques  while  the  particles  are  embedded  in  the  matrix,  is  that the surrounding bulk material will contribute to the analysed signal- limiting, for example, the quantification of the composition of particles.

  6. 5. Synthesis and Characterisation of Non-Evaporable Getter Films Based on Ti, Zr and V

    University essay from Plasma och beläggningsfysik; Tekniska högskolan

    Author : Erik Enqvist; [2011]
    Keywords : NEG; LHC; Sputtering; Sticking probability; ESD; coating;

    Abstract : Non-evaporable getters (NEG) are widely used in ultra high vacuum (UHV) systems for particle accelerators to assure distributed pumping speed. By heating the NEG to an activation temperature, the oxide layer on the surface dissolves into the material, leaving a clean (activated) surface. READ MORE
