  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. Robust TCO’s for CIGS solar cells based on indium tin oxide

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Julia Nilsson; [2022]
    Keywords : photovoltaics; solar cells; thin film photovoltaics; PV; TCO; transparent conductive oxide; indium tin oxide; ITO; CIGS; solar power; sputtering; RF sputtering; radio frequency sputtering;

    Abstract : The increasing energy demand, combined with the use of harmful non-renewable energy sources calls for the search of alternative methods to cover our energy need.Renewable energy can be harvested in different ways, through the movement of wind and water, biomass, or directly from the rays of the sun, as in the case of photovoltaic (PV) devices.

  4. 3. Carbon-coated Lead Halide Perovskite Quantum Dots and Copper(I)Iodide Coated Copper Nanowire Electrodes for Flexible Solar Cells

    University essay from KTH/Tillämpad fysik

    Author : Albin Andersson; [2022]
    Keywords : Nanotechnology; solar cells; perovskite; quantum dots; nanowire; thin film electrodes; nanoteknologi; solceller; perovskit; kvantprickar; nanotrådar;

    Abstract : Lead Halide Perovskite is emerging quickly as a promising material for the future solar cellsthanks to their inherent good optoelectrical properties along with their cheap and facile fabri-cation. However, their main drawback before commercialization is their weak stability. READ MORE

  5. 4. Development of Test Rig and Experimental Evaluation of Hydrostatic Bearings for an Axial Flux Machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Amir Avdic; Kishore-Babu Vejendla; [2022]
    Keywords : viscous losses; hydrostatic bearing; hydrodynamics; thin oil film.; Viskösa förluster; generator; hydrostatiska lager; hydrodynamik; tunn oljefilm.;

    Abstract : A novel electric machine design, similar to an axial flux machine, incorporates hydrostatic bearings to increase efficiency and stability of said machine. In this thesis, the feasibility of a hydrostatic solution is explored and evaluated by development, manufacturing, and assembly of a test rig, as well as running experimental tests with it.

  6. 5. 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
