Adamantyl Side Chains as Anti-Aggregating Moieties in Dyes for Dye-Sensitized Solar Cells
Almenningen, David Moe; Haga, Brita Susanne; Hansen, Henrik Erring; Buene, Audun Formo; Hoff, Bård Helge; Gautun, Odd Reidar (Peer reviewed; Journal article, 2022)Designing and evaluating novel dye concepts is crucial for the development of the field of dye-sensitized solar cells (DSSCs). In our recent report, the novel concept of tethering the anti-aggregation additive chenodeoxycholic ... -
Effect of seven different terthiophene π-spacers on dye performance in dye-sensitized solar cells
Almenningen, David Moe; Hansen, Henrik Erring; Buene, Audun Formo; Hoff, Bård Helge; Gautun, Odd Reidar (Journal article; Peer reviewed, 2022)To ensure high photocurrents from dye-sensitized solar cells (DSSC), it is important that the dye absorbs as much of the energy from the sunlight as possible. To achieve a wide absorption and cover larger parts of the solar ... -
Effect of thiophene-based π-spacers on N-arylphenothiazine dyes for dye-sensitized solar cells
Almenningen, David Moe; Hansen, Henrik Erring; Vold, Martin Furru; Buene, Audun Formo; Venkatraman, Vishwesh; Sunde, Svein; Hoff, Bård Helge; Gautun, Odd Reidar (Peer reviewed; Journal article, 2021)To study the effect of π-spacers on dye performance in DSSC, five novel phenothiazine dyes have been prepared where the number of successive thiophenes in the π-spacer was increased from zero to four. Additionally, a dye ... -
Exploration of σ-hole interactions and their effects in planarisation of the π-spacer in triarylamine dyes in Dye-sensitised solar cells
Wexsahl, Sigrid Jæger (Master thesis, 2022) -
First Report of Chenodeoxycholic Acid–Substituted Dyes Improving the Dye Monolayer Quality in Dye-Sensitized Solar Cells
Buene, Audun Formo; Almenningen, David Moe; Hagfeldt, Anders; Gautun, Odd Reidar; Hoff, Bård Helge (Journal article, 2020)Chenodeoxycholic acid (CDCA) is the most used anti-aggregation additive in dye-sensitized solar cells since its introduction to the field in 1993. However, effective suppression of dye aggregation comes at the cost of ... -
Investigation of the π-Spacer through Synthesis and Characterization of Phenothiazine Dyes for Dye-Sensitized Solar Cells
Almenningen, David Moe (Master thesis, 2018)The search for new ways of harvesting energy from the sun led to development of dye-sensitized solar cells (DSSC) by O Regan and Grätzel in 1991. These solar cells are built up by a nanoporous semiconductor, a dye that is ... -
Investigations of acetylene linkers and bulky imidazoles in phenothiazine based dyes for DSSC
Hansen, Ruben Åge (Master thesis, 2022)Abstract will be available on 2024-07-01 -
Strategies for successful Suzuki-Miyaura cross-couplings with thienylboronic acids: From model studies to dye structures
Strømsodd, Eivind Andreas; Buene, Audun Formo; Almenningen, David Moe; Gautun, Odd Reidar; Hoff, Bård Helge (Peer reviewed; Journal article, 2023)Suzuki-Miyaura cross-coupling is a convenient way for preparing thienyl containing dyes and bioactive molecules. However, reactions with thienylboronic acids can be troublesome. To understand these reactions in more depth, ... -
Syntese og karakterisering av triarylamin-fargestoff med adamantyl sidegrupper for DSSC.

Synthesis of Novel 3,6-Dithienyl Diketopyrrolopyrrole Dyes by Direct C‒H Arylation
Yemene, Amsalu Efrem; Venkatraman, Vishwesh; Almenningen, David Moe; Gautun, Odd Reidar; Hoff, Bård Helge (Peer reviewed; Journal article, 2020)Direct C-H arylation coupling is potentially a more economical and sustainable process than conventional cross-coupling. However, this method has found limited application in the synthesis of organic dyes for dye-sensitized ... -
Synthetic Efforts to Investigate Structure-Property Relationships in Dyes for Dye- Sensitized Solar Cells
Almenningen, David Moe (Doctoral theses at NTNU;2022:300, Doctoral thesis, 2022)With the backdrop of human-induced global warming in mind, the need for sustainable energy has never been larger. The Intergovernmental Panel on Climate Change presented in their recent assessment report that global warming ... -
