6. Charge transfer states at polymer solar cell interfaces : Insights from atomic-scale modeling
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

7. A photodegradation study of conjugated polymers for organic solar cells by absorption spectroscopy and atomic force microscopy
University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Abstract : The effect of light exposure in ambient air on thin films made from an electron acceptor polymer poly{[N,N'-bis(2-octyldodecyl)naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5'-(2,2'-bithiophene)} (N2200), an electron donor polymer Poly[[2,3-bis(3-octyloxyphenyl)-5,8-quinoxalinediyl]-2,5-thiophenediyl] (TQ1) and their blends, has been studied using UV-vis spectroscopy and Atomic Force Microscopy (AFM). For solutions of TQ1, N2200 and blends, the linearity of the Beer-Lambert law for absorption spectroscopy has been verified. READ MORE

8. Design, production and evaluation of cross linked target proteins to an affibody-based carrier framework aimed for affinity protein: antigen structure determination using single particle Cryo-EM
University essay from KTH/ProteinvetenskapAbstract : Small proteins are difficult to study at high resolution with single-particle cryo-electron microscopy (cryo-EM). In general, sample properties such as large size (> 80 kDa), symmetry and rigidity are key to utilize this technology. READ MORE

9. Electrical performance study of organic photovoltaics for indoor applications : with potential in Internet of Things devices
University essay from Karlstads universitetAbstract : The evolution of the internet of things (IoT) opens the market opportunity for organic photovoltaic cells, especially for indoor applications where the lifetime of the organic cells is longer than outdoor. For example, IoT requires off-grid energy sources for many devices with low power consumption. READ MORE
