Rhodamine 6G dyes are low-cost, highly soluble fluorescent dyes frequently utilized as laser dyes, chemical sensors, and as tracer dyes in the determination of the direction and rate of flow of water. In this study, the photophysical properties of three rhodamine 6G dyes, bearing phenyl , furan ), and 5-hydroxymethyl furan , and their metal complexes were investigated using ultraviolet-visible (UV-vis) spectroscopy, fluorescence spectroscopy, fluorescence lifetime, and Fourier transform infrared (FTIR) measurements. Rhodamine 6G dyes and their complexes were subsequently applied as sensitizing dyes in the fabrication of dye-sensitized solar cells, and the solar to electric power efficiency and electrochemical impedance spectroscopy measurements were performed. The solar to electric power efficiency values of the metal complexes of the rhodamine 6G dyes were higher than those of the devices fabricated with only rhodamine dyes without copper (II). The most significant change was observed in rhodamine P41 with a 30% increase in solar to electric power efficiency when the dye was conjugated to the copper ion.
罗丹明6G染料是低成本、高溶解性的荧光染料，经常用作激光染料、化学传感器以及用于测定水流方向和流速的示踪染料。在本研究中，使用紫外可见（UV-vis）光谱、荧光光谱、荧光寿命和傅里叶变换红外（FTIR）测量，研究了三种带有苯基、呋喃基和5-羟甲基呋喃基的罗丹明6G染料及其金属配合物的光物理性质。随后，罗丹明6G染料及其配合物被用作染料敏化太阳能电池制造中的敏化染料，并进行了太阳能到电能效率和电化学阻抗谱测量。罗丹明6G染料金属配合物的太阳能到电能效率值高于仅使用不含铜（II）的罗丹明染料制造的器件。当染料与铜离子共轭时，在罗丹明P41中观察到最显著的变化，太阳能到电能效率提高了30%。
