Research Interest
My research focuses on the area of fabrication of nanomaterials for a variety of solar energy-related applications. The main research studies focus on 1) Fabrication of various nanostructured materials, 2) Control of associated parameters in order to achieve desired morphology and structure of the obtained product, and desired optical and electrical properties of the materials, and 3) Development of solar energy conversion into other forms of energy, e.g. heat and electricity, and as a photocatalyst based on fabricated nanomaterials.
