Research

Dr. Mohammadi’s research encompasses the physics, materials chemistry and materials science and engineering of nanomaterials for sustainable and renewable energy systems, particularly solar cells and biomedical systems.

Sustainable and Renewable Energy Systems: Solar Cells

His current research focuses on mesoscopic perovskite and nanostructured dye-sensitized solar cells (PSCs and DSCs, respectively). He has invented a low-cost aqueous paste for deposition of nanostructured and mesoscopic TiO2 films. He demonstrated using new titania-based nanostructures as the light absorber and scattering materials, including TiO2-CNT and TiO2-rGO hybrids, corn-like nanowires, dandelion-like particles, hollow spheres, skein-like nanotubes, and nanocubes. These advances showed that the properties of these nanomaterials are superior, so that they can reveal their novel properties for operation in solar cells. DSC device with efficiency over 10% was developed through band gap tuning and engineering of charge transport and light scattering using the nanostructures. Highly stable quasi-solid-state DSC was also presented by a new gel polymer electrolyte. Novel configurations of PSCs have been designed through energy level matching and introduction of new hole-transporting materials (HTMs), electron transporting material (ETMs) and buffer layers including metallic phthalocyanine, graphene oxide (GO) and its derivatives. HTM-free PSCs based on fully printable components (i.e., carbon-based PSCs) with long-term stability was also developed.

Biomedical Systems

He has developed hydroxyapatite (HA)-based systems in the forms of scaffolds and coatings on titanium alloy implants with good mechanical property and improved cell attachment and bone regeneration. BiodegradableHA-reinforced polycaprolactone nanocomposites composed of either HA nanoparticles or HA nanorods have been fabricated for orthopaedic applications and maxillofacial surgery. The enhanced bone regeneration and mechanical properties of the nanocomposites raised by a new in-situ fabrication method. A new Ti–6Al–4V implant containing HA-CNT coating has been presented for excellent cell adhesion and bone growth process.
