 1- Triboelectric Nanogenerators

Triboelectric nanogenerators (TENGs) can harvest mechanical energy through coupling triboelectric effect and electrostatic induction. Typically, TENGs consist of organic materials, however on account of the potentially wide range of applications of TENGs as the self‐powered portable/wearable electronics, biomedical devices, and sensors; semiconductor metal oxide materials can be promising candidates to be incorporating in TENG structure.                                                   



2- Characterization of Perovskite Solar Cells
3- All Oxide Solar cells
Recently, a new field in photovoltaics has emerged, focusing on solar cells that are entirely based on metal oxide semiconductors. The all-oxide PV approach is very attractive due to the chemical stability, nontoxicity, and abundance of many metal oxides that potentially allow manufacturing under ambient conditions.

4- Bio-Molecule-Sensitized Nanostructured Solar Cells

Photosynthesis based on pigment-protein system provides the basic energy source for vitally all organisms. Our studies focuses on four natural dyes including green fluorescent protein (GFP), bacteriorhodopsin, chlorophyll extracted from microalgae, and Marshmallow extract to imitate photosynthesis process in bio-molecule-sensitized solar cells.


5- Optical Design of Nanostructured Photoanodes of Solar Cells

Light scattering design in the dye and quantum dot sensitized solar cells is one of the main concerns in enhancing the light harvesting efficiency and also improving the power conversion efficiency. Our studies focuses on the theoretical analysis to calculate the dependence of the light scattering efficiency in dye solar cells employed scattering agents with various sizes and morphologies incorporated in nanostructured photoanodes with different designs. These studies can provide a complete data base for enhancing the optical properties of the photoanodes of various types of solar cells, employing nanostructures as scattering centers.

6- Photoelectrochemical Characterization of the Nano-crystalline Photoanodes

The localized distributed trap states in the energy band levels of nanocrystalline photoanodes play an important role in transport features in the photoanodes of nanostructured solar cells. We have developed photochemical methods to characterize and investigate on surface and bulk traps in energy levels of TiO2 nanostructures based on different morphologies employed as photo-electrode of dye-sensitized solar cells. We have started our studies about different type of photoanodes.
