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

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

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

    Sammanfattning : 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.

    Sammanfattning : In today’s society many non-renewable and environmentally harming energy sources are used to facilitate people’s everyday energy demands. This causes ecosystems to break down, global temperatures to rise, pollution and many more critical long lasting problems. LÄS MER

  5. 4. Willingness to pay for improved maize seeds among smallholder farmers : a study of the input factor market in Kenya

    Uppsats för yrkesexamina på grundnivå, SLU/Dept. of Economics

    Författare :Anna Lenksjö; Henrik Nordzell; [2014]
    Nyckelord :Economics; Willingness to pay WTP ; Factor market; Kenya; Embu; Bondo; Smallholder farming; Inputs; Soil fertility management; Improved maize seeds; OPV; Hybrids;

    Sammanfattning : Kenya is considered to be a developing country. This means that basic needs such as nutrition are not met for an extended period of time (www, Sida 1, 2012). Approximately half of the population is living under the poverty line (www, CIA 1, 2012). Agriculture is the largest sector in the country, employing 75% of the population. LÄS MER

  7. 5. Roll-to-Roll Embedding of Conductive Sintered Silver Grids

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Ashish Kumar Pagudala; [2012]
    Nyckelord :;

    Sammanfattning : R2R embedding of conductive sintered grids: Within the organic light emitting diode(OLED) and organic photovoltaic(OPV) applications, to improve the efficiency of these devices, high conductive metal grids are required to replace tin-doped indium oxide (ITO) as an anode. High conductive metal grid, can be obtained by screen prinitng of the metal shunt lines which are several microns thick. LÄS MER
