Effect of Electron Donor Groups on Optoelectronic Properties of Betalain Dyes: A DFT Study
Tsere, Melkizedeck; Costa, Rene; Deogratias, Geradius; Pogrebnaya, Tatiana; Pogrebnoi, Alexander; Machunda, Revocatus; Al-Qurashi, Ohoud; Wazzan, Nuha; Babu, Nambury (wiley, 2025-05)A sensitizer is a vital component of dye-sensitized solar cells(DSSCs); it absorbs incident photons, excites electrons, and facil-itates charge transfer to the semiconductor. In the present work,modification of betalain ... -
Enhancing the optoelectronic properties of blended triphenylamine-betalain based dyes through tailoring the anchoring unit: a theoretical investigation
Tsere, Melkizedeck; Costa, Rene; Deogratias, Geradius; Al-Qurashi, Ohoud; Wazzan, Nuha; Pogrebnaya, Tatiana; Pogrebnoi, Alexander; Machunda, Revocatus (Taylor & Francis, 2024-11-25)A series triphenyl-betalain organic dyes featuring carboxylic acid and nitro anchoring groups CH = C(X)COOH for the A1-X dyes and -CH = C(X)NO2 for the A2-X dyes, respectively, where X = CN, CH3, CCl3 and CF3 was evaluated ... -
Investigation of optoelectronic properties of triphenylamine-based dyes featuring heterocyclic anchoring groups for DSSCs’ applications: a theoretical study
Deogratias, Geradius; Al-Qurashi, Ohoud S.; Wazzan, Nuha; Seriani, Nicola; Pogrebnaya, Tatiana P.; Pogrebnoi, Alexander M. (Springer Nature Switzerland AG., 2020-08-05)Design and synthesis of new potent sensitizers are of interest for realization of high-efficiency Dye Sensitized Solar Cells (DSSCs). Modification of the triphenylamine-based dyes by introducing suitable anchoring groups ...
