  1. 36. 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. 37. Experimental study on the effect of rocket nozzle wall materials on the stability of methane

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

    Author : Thomas L. Holmboe; [2023]
    Keywords : Methane; pyrolysis; catalysis; nickel; coke deposition; chemical modelling; GRI3.0; rocket nozzle; regenerative cooling;

    Abstract : There has recently been an increased interest in methane as a rocket propellant due to its physical properties as well as the possibility of in-situ resource utilization in places like Mars. As part of ESA’s Future Launcher Preparatory Program, KTH in cooperation with GKN Aerospace has started the MERiT program, which seeks to study the characteristics of methane under conditions found in rocket nozzle cooling channels.

  4. 38. Investigation of plasma cleaning on molybdenum crystals for diagnostic mirrors in fusion devices

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

    Author : Hafssa Laabadi; [2023]
    Keywords : ;

    Abstract : In the long-term energy scenario, nuclear fusion is a promising low-carbon and sustainable energy source. The unavoidable exposure of the wall materials to the plasma is a big challenge in realizing a fusion reactor. The plasma-facing components (PFCs) in the reactor wall will experience erosion deposition in the surface materials. READ MORE
