Professional Summary

Five years of research experience in Third Generation Solar Cells (Dye-Sensitized Solar Cells, Perovskite Solar Cells, and other device fabrication). Completed PhD - September 2020. 34 papers in peer-reviewed International Journals. Have done a part of my PhD work at Norway as an exchange student for a total period of 1 year. 8 years of experience in synthesizing and characterizing different nanostructures through wet chemical methods: Solvothermal, microwave-assisted synthesis, and light-induced reduction techniques. Experience in preparing thin films through physical processes such as thermal evaporation systems and Cold Plasma Chamber. Developed in-house Solar Simulator for the testing of solar cells. Managed hands-on training sessions for bachelor's and master’s students on the fabrication of Dye-Sensitized Solar Cells and Characterization Techniques. Presented research results at 2 International arena’s – Norway & Sri Lanka. Handled characterization techniques: Raman, UV-Vis spectroscopy, Photo Luminescence, and Keithley source meters for Current-voltage characteristics.
