Determination of chemical and optical properties of 2d hybrid perovskite [C6H10N2]PbBr4 and [C6H10N2]PbI4 in liquid form and crystal form under UV-VIS, FTIR, and XRD as a material for solar cell / Wan Hanis Lukman Wan Ismail

A new material, perovskites, is introduced, which experts believe may provide the most exciting potential for solar cells in the near future. However, perovskite cells' strength and stability must be addressed. Despite several attempts to make perovskite solar cells in ambient air, the power conversion efficiency remains poor as the material’s stability tend to get influenced by the normal atmosphere. In this thesis, a 2D hybrid perovskite was explored and alternatively generated by using reflux technique in ambient air. The generated material was systematically investigated as a promising light-harvesting material for perovskite solar cells. Generally, the performance of the formed 2D perovskite was examined under Ultraviolet–visible spectroscopy, Fourier-transform infrared spectroscopy, and X-ray diffraction. The optical energy band measured for two samples of 2D perovskite was 3.69 eV and 2.94 eV. The presence of N-H, N-H bonding & aromatic ring (Ar-H) in the formed sample was analyzed by Fourier-transform infrared. Under X-ray diffraction, both sample exhibit well-crystallized & equally spaced in the diffraction narrow peaks. The results demonstrate that the 2D sample fits the requirements for the light-harvesting material.
