An overview of the project:

The prosperity of human society largely depends on a safe energy supply, and fossil fuels are the most reliable source of energy. However, as a source of non-renewable energy, the depletion of fossil fuels is inevitable in this century to address this problem. Renewable energy, especially solar energy, has attracted considerable attention, as it directly converts solar energy into electric energy without leaving any impact on the environment. In the past various optical devices such as organic and inorganic solar cells, 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 local and other business applications. 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 the advantage of being lightweight and flexible over traditional solar silicon cells. Among all organic solar cells, dye-sensitive solar cells (DSSCs) were the most efficient and easily implemented technology compared to other organic dye inductors. DSSCs made cost-effectiveness and absorption transactions very high (~ 105 M-1 cm1), expanding absorption range in a visual area, near-infrared and excellent photography sensitivity, high Incident photon to converted electron (IPCE) which is capable of a wider area of wavelength which will then increase the efficiency of turning light into electricity for cyanin dyes make it a potential filters to provide a more efficient and metal-free light sensor for DSSCs. This is to overcome the defects of electron liquids used in DSSCs such as leakage of toxic organic solvents that cause environmental pollution and evaporation of volatile iodine will increase internal resistance to solar cells generally by reducing the concentration of carriers of the charge. Research has been conducted to develop non-conventional electrolytes such as Room-temperature ionic liquids (RTILs) and semi-solid and solid electrolytes. Therefore, developing light probes that have the efficiency and ability to harvest light in different areas of the solar spectrum and safe electrolytes with maximum efficiency to convert light to electricity remains the main challenge in enhancing the performance of DSSCs.

The project's objective is:

Test the efficiency of new nano-composite buildings of cyanine pigments, nanoscale extract oxide, and ion liquids (ILS) based on chitosan (IL-CS), as new probes for light and electrolytes, new raw materials, in the manufacture of DSSCs more efficient and high strength. The synthesized membranes of biopolymer, chitosan, ion-modified fluids (ILS) will be developed which are either used as additives to support new sensors of light from cyanine pigments or zinc-nano oxide modified cyanide pigments to synthesize (cyanin pigments).
