Functionalized oligothiophenes for application in organic solar cells
(Universität Ulm, 2016-04-28)
The steady increase in power conversion efficiencies (PCE) of donor/acceptor bulk hetero-junction (BHJ) organic solar cells (OSC) over the recent years was made possible by systematic improvement of the donor materials ...
Fused S,N-heteroacenes and thiophene-substituted Ruthenium(II) complexes for organic solar cells
(Universität Ulm, 2016-07-05)
The objective of this thesis was the preparation of functionalized thiophene-comprising oligomers and Ru(II) sensitizers for application in organic solar cells. As electron-rich unit S,N-heteroacenes were implemented in ...
Proline-Quaterthiophene hybrids: Synthesis and self-assembly
(Universität Ulm, 2017-02-01)
The aim of this thesis was to synthesize new asymmetric pi-conjugated A-B systems, which are able to self-assemble in chiral suprastructures due to the presence of a single amino acid and to investigate them with respect ...
Donor-acceptor oligomers for application in organic solar cells: synthesis, characterization, device fabrication
(Universität Ulm, 2017-04-12)
The aim of this work is the synthesis of novel, structurally-defined, and D/A-substituted oligothiophenes for utilization as donor material in solution-processed bulk-heterojunction solar cells (BHJSC). Furthermore, the ...
Synthesis and properties of fully conjugated cyclo[n]thiophenes and investigation into a boron-templated aryl-coupling method
(Universität Ulm, 2016-05-30)
Series of fully alpha-conjugated cyclooligothiophenes C[n3]Ts with n = 3, 4, 5, 6, 7, 8, and 9 have been synthesised via a platinum templated cyclisation method and caracterised. Comparison with other C[n]Ts with different ...
