Highly transparent dye-sensitized solar cells with UV-absorbing fluorene dyes and tetramethylthiourea electrolytes.

ABSTRACT: This study demonstrates the development of highly transparent dye-sensitized solar cells (DSSCs) through the strategic combination of UV-absorbing, metal-free dyes and a novel non-iodine-based electrolyte system. We systematically investigated four UV-absorbing dyes - FCA, FQA, FPCN, and FFCN - with the FPCN emerging as the optimal candidate, demonstrating superior visible light transmittance while maintaining effective power conversion efficiency (PCE). When coupled with a tetramethylthiourea/tetramethyl formamidinium disulfide (TMTU/TMFDS²⁺) electrolyte system, the FPCN-sensitized solar cells achieved remarkable visible light transmittance (VLT) exceeding 68% alongside a PCE of 1.58%, surpassing the performance metrics of conventional [Formula: see text] systems.
