  1. 11. Linearization of Resistive Digital-to-Analog Converter for RF-Applications Using Compensator and Digital Predistortion

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Henrik Eklund; [2021]
    Nyckelord :DAC; RDAC; DPD; Linearization; Digital-to-Analog Converter; Resistive Digital-to-Analog Converter; Digital Predistortion;

    Sammanfattning : High-speed digital-to-analog converters are critical components in many radiofrequency (RF) applications. The resistive DAC (RDAC) architecture is suitable for high-speed implementation in extremely scaled digital circuit nodes. LÄS MER

  5. 14. Electrical analysis of interface recombination of thin-film CIGS solar cells

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Henrik Lotse; [2020]
    Nyckelord :interface recombination; SCAPS; activation energy; temperature dependent IV; dominant recombination path;

    Sammanfattning : In this master thesis, electrical characterization of thin film CuInxGa(1−x)Se2 solar cells produced by Midsummer AB were performed with the aim of determining the dominant recombination path of these cells. Current-Voltage (IV), Quantum Effinciency (QE), temperature dependent IV (IVT) and Drive-Level Capacitance Profiling (DLCP) was used with the objective to investigate the dominant recombination path as well as provide some insight of the solar cells in order to create a baseline model using the modelling software SCAPS (Solar cell CAPacitance Simulator).

  7. 15. Effect of Shading on Thin Film Modules

    Master-uppsats, Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Författare :NISTHA MISHRA; [2020]
    Nyckelord :Shading Effect on Thin Film Modules;

    Sammanfattning : The Photovoltaic (PV) systems and the semiconductor PV technologies are heavily impacted by shading conditions; total or partial. Nearby residential buildings, commercial buildings, objects, etc. are likely to cause shade on the PV installations. LÄS MER
