1. Återvinning av solcellsmoduler i Sverige : En undersökning av de energitekniska, ekonomiska och politiska förutsättningarna
Uppsats för yrkesexamina på avancerad nivå, Mälardalens högskola/Akademin för ekonomi, samhälle och teknikSammanfattning : The solar industry is one of the fastest-growing energy industries in the global market. The reason is a combination of the falling prices of modules and inverters and increased conversion to fossil-free energy production. LÄS MER
2. Homebuilt reactor design and atomic layer deposition of metal oxide thin films
Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologiSammanfattning : This research thesis covers work done on building an atomic layer deposition (ALD) reactor followed by the development and optimization of an ALD process for indium oxide thin films on crystalline silicon substrates from new precursors using this new homebuilt cost-effective tool. This work describes the design, building and testing of the ALD system using an indium triazenide precursor and water in a novel precursor combination. LÄS MER
3. Characterization of Silicon Waveguides For Non-Dispersive Infrared Gas Sensors
Master-uppsats, Luleå tekniska universitet/RymdteknikSammanfattning : Carbon dioxide is an important gas for life on Earth. But as human activities have been expanding throughout modern history, the CO2 concentration in the atmosphere is increasing. High concentrations of carbon dioxide can lead to various consequences, such as climate change and poor air quality both indoors and outdoors. LÄS MER
4. A comparison study of PV and battery technologies for EWB off-grid electrification projects in Sub-Saharan Africa
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Only 10 % of the rural population in Sub-Saharan Africa has access to electricity. At the same time the Sub-Saharan countries are close to the equator and get many sun hours a day, leading to a huge potential for solar energy. LÄS MER
5. A Meta-Analysis on Solar Cell Technologies
Kandidat-uppsats, Mittuniversitetet/Avdelningen för elektronikkonstruktionSammanfattning : 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. LÄS MER
