Student from the college of education for pure sciences participates in the TMREES 2021 Conference


Nada Adnan Sabri, a master’s student from the department of physics at the college of education for pure and applied sciences (Ibn al-Haitham) along with her supervisor, Prof. Dr. Hadi Jabbar Majebel, have participated recently in the proceedings of the Annual Conference of Technologies and Materials for Renewable Energy, Environment and Sustainability (TMREES-2021) held in Greece and sponsored by the European Academy for Sustainable Development (EURACA). The student presented a research paper entitled (Theoretical Studies of Electronic Transition Characteristics of Sensitizer Molecule Dye N3-SnO2 Semiconductor Interface) that was ranked in the first place.

The study included an analysis of the electron transfer feature for (N3 molecule) that touches the (SnO2) semiconductor by the use of a theoretical model based on calculating the electron energy and the transitional energy with the use of various solvents, such as: (1,2-Dimethoxyethane, Ethanol, Methanol,  Chlorobenzene, 2-Methoxyethanol, Pyridine and N,N-Dimethylformamide). The researcher found that the transition capacity is strong for the refractive index and for the stable electrical insulation, while it is increasing with an increase of the stable electrical insulation and it is decreasing in the case of the refractive index, as well as she noted that the transitional energy is at the highest rate with the methanol solvent, and at the lowest rate with the chlorphenesin solvent, in addition to an increase in the electronic rate with a reduced momentum energy and an increase in pairing strength.
