  1. 1. Aerial Thermography Inspections in Large-Scale PV Plants

    Master-uppsats, Högskolan Dalarna/Energiteknik

    Författare :Salvador Selva Marti; [2018]
    Nyckelord :Infrared thermography inspection; large-scale PV plants; drone; unmanned aerial vehicles; Quintas Energy; operation and maintenance; monitoring operations;

    Sammanfattning : In order to successfully compete against the use of fossil fuels to generate electricity, one of the challenges in the photovoltaic (PV) business currently in focus is on the asset management of large PV plants, in which developing control techniques to prognosticate and evaluate the future energy performance will be essential. Infrared thermography inspections can give meaningful support to assess the quality and performance of PV modules. LÄS MER

  2. 2. SnOx electron selective layers for perovskite/silicon tandem solar cells using atomic layer deposition

    Master-uppsats, KTH/Energiteknik

    Författare :Lisa Anna Zafoschnig; [2018]
    Nyckelord :;

    Sammanfattning : In this work the application of ALD deposited SnOx films as electron transport layers in perovskite solar cells is analysed. Processes to fabricate homogeneous, transparent and conductive tin oxide films were developed on an Oxford Instruments FlexAL tool using a TDMASn precursor and H2O as oxidiser. LÄS MER

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Författare :Wilhelm Johansson; [2018]
    Nyckelord :Thin films; Coatings; Metal oxides; UV-protection; UV-cutoff; Optical bandgap; Renewable Energy; Photoluminescence; PV-modules; Energy Efficiency; Life expectancy; Tunnfilm; metalloxider; UV-skydd; UV-kant; Optiskt bandgap; Förnyelsebar Energi; Fotoluminiscens; Solcellsmoduler; Solceller; Verkningsgrad; Teknisk Livslängd;

    Sammanfattning : Thin film coatings of ZnO, TiO2, CeOX and BiOX have been deposited on soda lime silica glass through spray pyrolysis. The effects on the optical properties of the coated glass, as well as the possible impacts on the life expectancy and energy efficiency of PV-modules have been studied. LÄS MER

  4. 4. Assessing the feasibility of implementing DC-microgrids in addition to USB-C and rooftop PV in households

    Master-uppsats, KTH/Energiteknik

    Författare :Miguel Igual Escriche; [2018]
    Nyckelord :;

    Sammanfattning : This Thesis’s frame is the feasibility of DC-microgrids at buildings environment. Nowadays, there is plenty of literature available regarding the benefits of implementing DC at buildings instead of AC as a means of optimizing photovoltaic generation PV on the grounds of minimizing conversion losses, with an overall energy saving of about 5-12% [1] [2].

  5. 5. Miljökrav på solceller : En utredning om koldioxidutsläpp från kristallina kiselsolceller

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Kristin Vanky; [2018]
    Nyckelord :;

    Sammanfattning : This master thesis is an investigation of environmental sustainability of photovoltaic (PV) modules. The purpose is to examine how purchasers of PV systems could put requirements on the modules so that their life-cycle carbon dioxide emissions reduces in the most effective way. LÄS MER
