1. 1. Simulations of energy efficient windows in a historical building located in mid-Sweden

   Magister-uppsats, Högskolan i Gävle/Energisystem och byggnadsteknik

   Författare :Iñigo Medrano Eraso; [2023]
   Nyckelord :Amorphous silicon; photovoltaic; windows; Gävle townhall; thermal comfort; energy efficiency; solar panel windows; IDA ICE. ;

   Sammanfattning : Amorphous silicon photovoltaic windows intend to not only improve thethermal bridge that windows represent but also to collect energy from theradiation incident on the windows themselves. This kind of windows can beapplied anywhere, however to maximize the benefit these can bring it isrecommended for sun-oriented façades. LÄS MER

3. 2. Energy harvesting with solar cells for wireless alarm nodes

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Tobias Olofsson; [2018]
   Nyckelord :energy harvesting; solar cells; alarm nodes; Technology and Engineering;

   Sammanfattning : Energiförbrukningen i elektronikprodukter minskar samtidigt som prestandan för solceller hela tiden ökar. Nya solcellstyper med lägre priser skapar nya möjligheter för använding även i små elektronikprodukter. Att samla energi från omgivningen, t.ex. LÄS MER

4. 3. A Meta-Analysis on Solar Cell Technologies

   Kandidat-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktion

   Författare :Farid Mohammadi; [2017]
   Nyckelord :Solar cell; Photovoltaics; Amorphous silicon; Monocrystalline silicon; Polycrystalline silicon; Cupper indium gallium selenide; Cadmium telluride; Thin film; Efficiency; Fill factor;

   Sammanfattning : The objective of this study is analysing the characteristics of five different solar cell technologies regarding their efficiency, fill factor, cost and environmental impacts and comparing their improvement records over years considering their efficiency. The five solar cell technologies of interest are amorphous silicon, monocrystalline silicon, polycrystalline silicon, cupper indium gallium selenide thin film and cadmium telluride thin film.

5. 4. Comparison of the performance of silicon and thin film solar cells at the laboratory of the University of Gävle

   Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

   Författare :Cristian Baena Juan; [2016]
   Nyckelord :solar cell performance; crystalline silicon; thin film CIGS; energy conversion efficiency; performance ratio;

   Sammanfattning : The huge environmental awareness emerging last years by reason of global warming and greenhouse effect, on one hand, and the need of finding other sources of energy production and conversion due to the declining of fossil resources and the increasing cost of this kind of energy resource, on the other hand, both have led position renewable energies as a powerful alternative on the energy production and conversion. PV-systems have emerged at an exponential rate in recent year as the main candidate and a satisfactory possibility with respect to environmental and economic sustainability. LÄS MER

7. 5. Energy Harvesting Device

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

   Författare :Driton Salihu; [2016]
   Nyckelord :Energy Harvesting; Rechargeable Batteries; Supercapacitor; ABB; PV; Solar cells; Radio Frequency; Piezoelectric; Thermoelectric generators; PMIC; Amorphous-silicon; Gallium-Arsenide; MPPT; PCB.; Technology and Engineering;

   Sammanfattning : This thesis evaluates the concept of Energy Harvesting as a power source for a serial measurement board used by ABB robots. A background study of possible energy harvesters is included, where the main focus is put on the overall function and what parameters determine the maximum generated power and efficiencies. LÄS MER
