Two novel ruthenium sensitizers containing unsymmetrical indeno[1,2-b]thiophene or a fused dithiophene unit in the ancillary ligand have been designed and synthesized. The photovoltaic performance of JK-188 using an electrolyte consisting of 0.6 M 1,2-dimethyl-3-propylimidazolium iodide, 0.05 M I2, 0.1 M LiI, 0.05 M guanidinium thiocyanate, and 0.5 M tert-butylpyridine in acetonitrile revealed a short-circuit
设计并合成了两种新型的钌敏化剂,它们在辅助配体中含有不对称的茚并[1,2- b ]噻吩或稠合的二噻吩单元。的光电性能JK-188使用由0.6M的1,2-二甲基-3-丙基咪唑鎓碘化物,0.05 MI电解质2,0.1M的LiI,0.05M的硫氰酸胍,和0.5M叔丁基吡啶的乙腈溶液揭示了短电路光电流密度为18.60 mA / cm 2,开路电压为0.72 V,填充因数为0.71,总转换效率为9.54%。使用由5 wt%聚偏二氟乙烯-共-六氟丙烯,0.6 M 1-丙基-2,3-二甲基咪唑碘化物组成的准固态电解质,该电池在60°C的光浸泡1000 h下表现出显着的稳定性,0.5 M N-甲基苯并咪唑和0.1 MI 2的3-甲氧基丙腈溶液,保留了97%的初始效率(7.38%)。
