21. Organic-inorganic hybrid perovskites as light absorbing/hole conducting material in solar cells
University essay from Fysikalisk kemiAbstract : Solar cells involving two different perovskites were manufactured and analyzed. The perovskites were (CH3NH3)PbI3 and (CH3NH3)SnI3. Both perovskites have a shared methyl ammonium group (MA) and are used as both light absorbing material and hole conducting material (HTM) in this project. READ MORE

22. Correlation of size and photoluminescence of single CdSe/ZnS quantum dots
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : In this thesis the correlation between size and emission wavelength of single CdSe/ZnS quantum dots (QDs) has been studied. Based on the quantum confinement model QDs of different size emit light of different wavelength. READ MORE

23. Measuring the efficiency and charge carrier mobility of organic solar cells
University essay from Institutionen för fysikAbstract : P3HT single layer, P3HT/PCBM bilayer and P3HT/PCBM inverted bilayer devices were produced by spin coating organic layers onto ITO patterned glass in air, and clamping it with an Au coated silicon wafer, as top electrode, at the end (Figure13). Normal and inverted bilayer devices were also fabricated with and without PEDOT:PSS. READ MORE

24. Fabrication and Optical Properties of ZnO Nanocrystal/GaN Quantum Well Based Hybrid Structures
University essay from Tunnfilmsfysik; Tekniska högskolanAbstract : Optical properties of hybrid structures based on zinc oxide nanocrystals (NCs) and Gallium Nitride quantum well (QW) has been studied. The ZnO NCs thin films on the top of GaN QW structures were fabricated using spin coating. The surface morphology was characterized by scanning electron microscopy (SEM). READ MORE

25. Optical Properties of Silica-Copper Oxide Thin Films Prepared by Spin Coating
University essay from Tillämpad optikAbstract : Optical properties of copper oxide nanoparticles in a silica matrix thin film have been investigated. Films were prepared on Si substrates from a sol-gel by spin coating. Four samples with different thicknesses, from 14,5-109 nm, were fabricated. Optical properties were measured with Variable Angle Spectroscopic Ellipsometry. READ MORE
