N2 - We present a straightforward synthesis of UV-harvesting dyes featuring a fluorene donor with different anchoring groups, such as cyano acetic acid, amino benzoic acid, and 2-methyl-quinoline-6-carboxylic acid (designated as FCA, FAB, and FQA, respectively). We comprehensively investigate the spectroscopic, electrochemical and colorific properties of these dyes and evaluate their suitability as photosenstizers in visually transparent and colorless dye-sensitized solar cells (DSSCs). FCA and FQA possessing planar geometries exhibit remarkably efficient collection of UV photons, leading to excellent power-conversion-efficiencies (PCEs) under UVA radiation. Furthermore, we explore the incorporation of the binary redox couple, (I−,Br−)/(I3−,I2Br−), to enhance the ability to transmit visible light, positively impacting their color rendering properties, while preserving their light harvesting capacities.
