Thesis Title: Fabrication and Characterization of Luminescent Solar Concentrator with the Simultaneous use of Organic Dyes and Organic-Inorganic Perovskite

Abstract: Nowadays, the use of Luminescent solar concentrators as an alternative to the use of photovoltaic technology in energy production is on the agenda. Many research groups are working to maximize the efficiency of these systems. In this research work, an attempt has been made to increase the efficiency of concentrators by using the two chromophores of Perovskite and Rhodamine b at the same time. The structural and optical properties of the synthesized Cs4PbBr6 Perovskites were investigated and it was shown that the Stokes shift of these perovskites is 24 nm, which is suitable to use in concentrators. Structural and optical studies of Rhodamine dyes have also shown this organic dye, like synthesized Perovskite, can be used in concentrators. In addition, a green industrial dye was structurally and optically tested and the possibility of using it in concentrators was proven. Then, using 3D printers, for the first time, luminescent solar concentrators with Perovskite, Rhodamine b and industrial green dyes were made. Fiber optic spectroscopy was performed from the edges of these concentrators. The solar cell was also characterized in the presence of Luminescent Solar Concentrators. The results obtained from the I-V diagram of the solar cell show that the efficiency of the solar cell in the presence of Perovskite, Rhodamine and Perovskite and Rhodamine mix were respectively 46.3%, 50.5% and 122.1% increased.
