1. Thin Indium Tin Oxide Layer Development for Crystalline Silicon/Perovskite Two Terminal Tandem Solar Cell
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : ITO is widely regarded as the optimal TCO for serving as front window layer in PSK/c-Si tandem solar cells. It is known to effectively mitigate several stability issues present in perovskite solar cells while demonstrating excellent lateral conductivities and optical transparency across the entire solar spectrum.

2. Reaction of Copper and Copper(I) Iodide with Iodine and Strong Field Ligands
Master-uppsats, KTH/Tillämpad fysikalisk kemiSammanfattning : Perovskit solceller (PSCs) är kända som 'ljusomvandling' enheter med ökad omvandlingseffektivitiet (PCE). PSCs är kända för detta flexibilitet och hög tolerans mot defekter och består av fem lager med olika material och egenskaper. LÄS MER
3. Niobium Ohmic Contacts for Cryogenic Indium Phosphide High-Electron-Mobility Transistors
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Ohmic contacts are crucial components in semiconductor devices such as transistors and diodes, and lowering their contact resistance is an important factor in device performance enhancement. This is especially important for low-noise amplifiers (LNAs) where device noise temperature decreases both directly and indirectly with decreasing contact resistance. 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. Optical active thin films on cover glass increasing the efficiency of photovoltaic modules.
Kandidat-uppsats, Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)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
