New series of soft materials based on ionic liquid–metal complexes for high-efficient electrolytes of dye-sensitized solar cells

摘要: A new series of soft materials were successfully achieved by a simple synthetic method in water. The coordination reactions task-specific ionic liquid with different metal oxides systematically investigated and analyzed. obtained ten liquid–metal complexes (ILMCs) developed for efficient electrolytes dye-sensitized solar cells (DSCs). ILMC-based DSCs exhibit superior photovoltaic performance the remarkable increases efficiencies multiple 1.46–2.63 compared an (IL) electrolyte without center. mechanism investigations clarified influences centers on conversion corresponding devices. high conductivity diffusion coefficient I3−, inhibited electron recombination low charge transfer impedance contribute to ILMC electrolytes. concept, composition, efficiency along easy fabrication qualify as promising high-efficient alternative DSCs.
