Model and Optimization of Dye-sensitized Solar Cell

The dye-sensitized solar cell (DSSC) consists of a nanoporous film with a large internal surface area covered with a layer of light-absorbing dye. The dyed layer converts the photons entering the nanoporous film into a charge. Standard DSSC are constructed from a nanoporous film consisting of powdered titanium dioxide dyed with ruthenium and an iodide/triiodide solution filled with a redox electrolyte solution. Based on the mathematical model of the DSSC developed by us, two experimental physical models were produced: with traditional parameters and with modified parameters with the help of the model obtained. The model with traditional parameters, as expected, has an efficiency of 9.89%. This figure is slightly different from the theoretical one. The model with modified parameters has a conversion efficiency of 11.58%. Photo electrochemical cells, such as dye-sensitized solar cells (DSSC), represent an alternative to existing p-n contact devices. These cells use a conductor - an electrolyte-contact in contrast to the classical solid contact. DSSCs are relatively inexpensive to produce and provide clean and inexpensive energy. In addition, electrical energy is formed without any chemical transfer of components in DSSC, which ensures the durability of cells. To date, the efficiency of DSSC is known between 7- 15%. For competitiveness with conventional photovoltaic cells, DSSC need to increase efficiency, stability and reduce production costs. Based on the practical results obtained, it can be concluded that further optimization of the model is possible. The DSSC is an attractive and promising device for use in solar energy. Recently, DSSCs have been widely researched for commercial use. The cost of commercial production of the DSSCs is assumed to be relatively cheap, because the materials used are relatively inexpensive and the assembly is relatively simple and easy.
