  1. 1. Organic Solar Cell Fabrication and Study on the Influence of Spin-dependent Processes on the Photocurrent using Spin-sensitive Techniques

    University essay from Uppsala universitet/Fasta tillståndets fysik

    Author : Ronja Olsmats Baumeister; Evelina Roxner; [2022]
    Keywords : EDMR; EPR; trEDMR; PEDOT:PSS; PCBM; P3HT; organic solar cells; osc; opv;

    Abstract : Research in recent years on novel materials in organic solar cells (OSCs) have contributed to a rapid advancement in OSC efficiency. Here, OSCs with the well-studied organic semiconductors poly(3-hexylthiophene):[6,6]-phenyl C60-butyric acid methylester (P3HT:PCBM) in a bulk heterojunction structure were prepared to establish a baseline procedure for fabrication and spin-sensitive spectroscopy.

  3. 2. Evaluation of solar powered systems in small scale UAV designs

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Lukas Girlevicius; [2022]
    Keywords : ;

    Abstract : Unmanned Aerial Vehicles (UAV) also know as drones are becoming increasingly present in modern societies. Despite their versatility and success in many areas, small scale UAVs which are nearly always battery powered and therefore have limited flight endurance. READ MORE

  4. 3. Stability of electron acceptor materials for organic solar cells : a work function study of C60/C70 derivatives and N2200

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Sebastian Ekhagen; [2019]
    Keywords : ;

    Abstract : Thin films of the fullerenes PC60BM and PC70BM and the non-fullerene N2200, three popular electron acceptor materials in organic photovoltaics, have been studied, using both the Kelvin probe method as well as ultraviolet photoelectron spectroscopy. With these methods the work function was measured, as well as the highest occupied molecular orbital (HOMO) onset. READ MORE

  5. 4. Characterizing particulate carbon using dielectric property measurements

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Madeleine Syk; Joakim Vollmer; [2018]
    Keywords : black carbon; elemental carbon; carbonaceous aerosols; soot; fullerene C60; multiwalled carbon nanotubes; mesoporous carbon; impedance; dielectric; snow melting; capacitance; waveguide;

    Abstract : Interest in effects of carbonaceous particles in the atmosphere has recently taken an upswing due to knowledge of how these particles affect our environment. Carbonaceous aerosols are characterized by their dark color, giving them the ability to absorb both incoming and outgoing radiation of all wavelengths in the atmosphere. READ MORE
