Research Interests 

I am currently a Ph.D. Candidate in Chemistry with Prof. Jean-Francois Morina and Prof. Anna Ritcey at the Department of Chemistry, Université Laval.  

I have graduated with a Bachelors' in Electrical and Electronics Engineering and a Master's in Energy Technologies with a master’s project in energy materials. 

My research interests are in the development of novel devices based on organic and metal oxide semiconductor materials for organic solar cells and/or supercapacitors based on low-cost manufacturing processes like solution-based methods/ printed & large area flexible electronics.

The master’s project was focused on the investigation of the effects of nanoparticle doping on the optical and electrical properties of metal oxide thin films under visible light exposure for solar cell applications. I have synthesised metal oxide thin films nanostructure from solution-based methods. The structured characterization techniques (XRD, FTIR, SEM and EDX) were used to confirm the formation of nanostructures and doping. The experimental work was aimed at using optical characterizations (PL, UV-DRS and UV-vis.) to observe the changes in the band gap, performance in visible spectra to find suitability for photovoltaics and in-depth electrical measurements under visible light exposure (Cyclic voltammetry, I-V characterization) using potentiostat, to analyse the photo-induced effects such as photo-activation, charge transfer/ charge-discharge/ charge storage/ electrochemical capacitance of metal oxide thin films. The optical properties of thin films demonstrated a change in band gap and improved performance in visible spectra after doping. The charge storage capacity of thin films shown significant improvement after doping and the improvement in the charge storage under visible light exposure was observed. One of the doped thin films shown an improvement of five times in charge storage capacity than the undoped Titania thin films under visible light exposure which made it a promising material for possible application in solar cells and supercapacitors. In this project, I was able to receive training in the synthesis/ fabrication of nanostructured materials/ thin-films and significant working experience in the different fabrication methods and characterization tools used for the characterization of thin films and organic solar cells. 

Further, I have broadened my research interests and knowledge in the area by attending courses and hands-on training sessions on flexible electronic devices (organic solar cells), CVD & PVD techniques, Printing techniques for solar cells, microelectronic devices and advanced characterization & data analysis techniques. I believe the skills and experiences gained during the course of the previous research training will be very much valuable in synthesis/ fabrication of metal halide perovskite thin films and characterizing the relationship between photophysics and thin films properties for the PhD project. 

I wish to carry out my PhD research project on the study the nanostructure formation in the organic semiconductor materials/ functional thin films and characterization of the optical and electrical properties for the fabrication of organic solar cells and energy storage devices. Which would require work in material synthesis, sample/thin film preparation, characterization of thin films, measurements under various conditions and data analysis.
