  1. 1. Mathematical modeling and analysis of hot carrier solar cells

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Benjamin van Dijk; [2023]
    Keywords : solar cell; nanowires; hot carrier; nanowire; analysis; mathematical model; trends; fermi function; reservoirs; Physics and Astronomy;

    Abstract : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. READ MORE

  5. 4. Integrated antenna switch for NB-IoT

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Fredrik Zetterblom; Yunus Dawji; [2018]
    Keywords : T R Transmit Receive switch; RF switch; integrated RF switch; Narrowband Internet of Things NB-IoT ; CMOS; frontend; Technology and Engineering;

    Abstract : Transistors are used in all digital devices today. The demand of faster and smaller devices such as mobile telephones and computers constantly drives the develop- ment of smaller transistor technologies. Transistors can also be used in analog applications. Today there are commercial chips with both radio and digital sys- tems in the same package. READ MORE

  6. 5. Theoretical investigations of stator iron losses in a 15 MW induction motor equipped with fractional conductor windings

    University essay from KTH/Elektrisk energiomvandling

    Author : Makhdoomzada Asadullah Siddiqui; [2011]
    Keywords : ;

    Abstract : Iron loss calculation in AC machines has aroused great interest over the years, in an attempt to make electrical machines more efficient. However, different iron loss models yield different results for the same machine, owing to their individual limitations. READ MORE
