The mutual solubility of Ionic Liquid and Water: Experiments and Correlations

Ionic Liquids (ILs) are known as green solvents. ILs can separate aromatic-aliphatic mixture as well as aqueous solution. The mutual solubility is the pre-requirement for the solvent selection in extraction based separation. The mutual solubility of IL and water with temperature variation is the prime objective. The experimental data can be correlated with Gibbs free energy models for the generation of binary interaction parameter.

Nanocrystalline substituted cobalt based metal oxides for oxygen evolution reaction: A prerequisite for photochemical water splitting

The project focuses on designing more advanced cobalt based metal oxides and substituting them with transition metals. Cobalt oxide based materials have been chosen because they are economical and have shown promising activity towards OER recently. Prepared materials will be used as oxygen evolution reaction (OER) electrocatalysts with the aim to get higher catalytic activity in terms of low overpotential and high current density. The catalytic OER on one hand will give oxygen and on other hand it will also provide cost-effective route for clean, renewable hydrogen fuel which will be able to reduce our dependency on fossil fuels and also result in minimizing the environmental pollution.

This project is funded by DST-SERB Extra Mural Research Grant.

Deposition and Characterization of Perovskite Solar Cells

This project will result into better understanding of Thin Films Technology and Perovskite solar cells. The project’s outcomes will highlight the issues and solutions regarding the stability, degradation mechanism, and improvement in the efficiency of the perovskite solar cells. Most importantly degradation study will provide a path to rectify the shortcomings of the perovskite solar cells and helps the researchers to prepare a better device.

Role of Swift Heavy Ion on the Performance of Perovskite Solar cell

Swift heavy ions (SHI) have found substantial use in the research and technology of materials analysis and modification. TiO2 thin films are of great interest and there is need to optimize its property for given application such as solar cells, sensor, and electrochromic materials. Engineering of a perfect TiO2 compact layer, known as blocking layer, is very important part of the perovskite solar cell or dye sensitised solar cell fabrication since the interface between TiO2 and FTO plays a significant role in power conversion efficiency. Blocking layer helps in the electron transportation and reduces the electron recombination losses.  Different materials have been investigated for this purpose e.g., ZnO, sandwich layer, TiO2 embedded in an insulating polymer derived ceramic, Graphene oxide mixed TiO2 and hybrid blocking layer. Properties of these oxide materials and their nano-composite can be tailored using Swift heavy ions. SHI irradiated transparent conducting oxide films have reported significant improvement in the adhesion as well as changes in optical, electrical, & structural properties and contact to the substrate . Therefore, in the present project it is expected that SHI will improve the TiO2 adhesion to the substrate and also helps in blocking the back travel of the electrons which will eventually enhance the solar cell efficiency.

This project is funded by Inter University Accelerators Centre (IUAC).
