Project Profile:

In the past various photonic devices such as organic, inorganic solar cells, and hybrid have been successfully manufactured and used. Despite the high conversion rate of silicon solar cells, the high unit cost and complex production process restricted their application only to aeronautical technology for domestic and other commercial applications, and recent research has focused on organic solar cells that have a low unit cost and are easy to manufacture. In addition, organic solar cells have their advantage as they are lightweight and flexible compared to traditional solar silicon cells. Among all organic solar cells, dye-sensitive solar cells (DSSCs) were the most efficient technology and easily implemented compared to other organic dye allergens. Cost-effectiveness, very high absorption factors (~ 105 M-1 cm1), expansion of absorption range in a visual area, near-infrared, excellent photography sensitivity, and high photon-to-electron conversion efficiency (IPCE) Which is capable of a wider area of wavelength which will then in turn increase the efficiency of turning light into electricity, for cyanin dyes make it a promising filter to provide a more efficient and metal-free light sensor for DSSCs to overcome the defects of electron fluids used in DSSCs such as toxic organic solvent leakage that cause environmental contamination and evaporation of volatile ion will increase internal resistance of solar cells generally by lowering the concentration of carriers. Research has been done to develop non-traditional electrolytes such as ion fluids at room temperature (RTILs). As well as semi-solid and solid electrolytes.

Therefore, the main challenges in enhancing the performance of DSSCs remain developing efficient light probes that can harvest light in different areas of the solar spectrum and safe electrolytes with maximum efficiency to convert light to electricity.

Project objectives:

The proposal aims to test the efficiency of new chitosan-based nanoscale pigments, nano oxide, and ion liquids (ILS) as new light probes and electrolytes, new raw materials, in the manufacture of more efficient and high-strength DSSCs. The membranes will be developed from biopolymer, chitosan, ion-modified fluids (ILS) that are either used as additives to support new sensors of light from cyanine pigments or zinc-nanoscale oxide modified cyanine pigments to synthesize (cyanin pigments (nanoscale zinc oxide)/IL L S) or used as electrolysis.
