  1. 1. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Salim Charkas; [2023]
    Keywords : Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

    Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

  3. 2. 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.

  4. 3. Determination of the inelastic mean freepath for SiO2 and the BBL polymer : A study with XPS and HAXPES

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Rickard Gauffin; [2022]
    Keywords : XPS; HAXPES; IMFP; Polymer;

    Abstract : This study targets methodology development using Photoelectron Spectroscopy (PES) as a tool for investigating material surfaces. When analysing samples with X-ray Photoelectron Spectroscopy (XPS) and Hard X-ray Photoelectron Spectroscopy (HAXPES), it is important to know the probing depth of the samples. READ MORE
