Estudo do espectro eletrônico da molécula ditienil-dicetopirrolopirrol com o uso da teoria do funcional da densidade dependente do tempo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em QuímícaUTFPR, 2020-03-19)
Using the time-dependent density functional theory, the S0→S1 electronic spectrum of the 2,5-dihexyl-3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione molecule (DPP2T) was investigated, analyzing the performance ...
Insights into the role of D-A-pi-A type pro-aromatic organic dyes with thieno[3,4-b]pyrazine as A acceptor group into dye-sensitized solar-cells. A TD-DFT/periodic DFT study
(2019)
Time-dependent density functional theory (TD-DFT)/periodic DFT calculations were performed to determine the role of pro-aromatic organic D-A-pi-A type dyes (the NL1-NL17 family) with Thieno[3,4-b]pyrazine (Tpy) as A acceptor ...
Reorganization energy for hole and electron transfer of poly(3-hexylthiophene) derivatives
(2016-09-02)
Poly(3-hexylthiophene) (P3HT) is a common material used as electron donor element in active layers of organic solar cells. Previous studies have shown that is possible to improve the electronic properties of the P3HT through ...
Theoretical evaluation of chemical substitutions along the main chain of poly(3-hexylthienylene-vinylene) for solar cell applications
(2018-02-01)
In order to improve the efficiency of bulk-heterojunction organic solar cells, one can try to optimize the active layer through the use of new materials that provide improvements in the parameters that influence the final ...
Formation of self-assembled monolayer of curcuminoid molecules on gold surfaces
(Elsevier, 2017)
We investigated the formation of self-assembled monolayers of two thiophene curcuminoid molecules, 2-thphCCM (1) and 3-thphCCM (2), on polycrystalline gold substrates prepared by immersion of the surfaces in a solution of ...
