Improvement of the electrolyte ionic conductivity in DSSCs application is important as it contributes higher solar conversion efficiency. In this article, the polyurethane acrylate (PUA) gel polymer electrolyte (GPE) system was further improved with the addition of an ionic liquid in terms of ionic conductivity and also photovoltaic performance. The PUA GPE system enhanced with 6 wt % of 1-butyl-3-methylimidazolium iodide (BMII) ionic liquid was found to produce the highest improvement (ionic conductivity) compared to the different content of BMII. Ionic conductivity of (4.17 ± 0.01) × 10^–4 S cm^–1 was observed at room temperature with the addition of 6 wt % BMII in the GPE system. Moreover, the DSSC utilizing the GPE with 6 wt % BMII produces the highest solar conversion efficiency of (5.72 ± 0.14)% corresponding with the J_sc of (23.03 ± 0.2) mA cm^–2 and V_oc of (0.54 ± 0.01) V.

在 DSSC 应用中提高电解质离子电导率很重要，因为它有助于提高太阳能转换效率。在本文中，聚氨酯丙烯酸酯 (PUA) 凝胶聚合物电解质 (GPE) 体系通过添加离子液体在离子电导率和光伏性能方面得到进一步改进。发现与不同的BMII含量相比，用6wt%的1-丁基-3-甲基咪唑鎓碘化物（BMII）离子液体增强的PUA GPE系统产生最高的改进（离子电导率）。离子电导率 (4.17 ± 0.01) × 10 ^–4 S cm ^–1在室温下观察到在 GPE 系统中添加 6 wt% BMII。此外，使用具有 6 wt % BMII 的 GPE 的 DSSC 产生 (5.72 ± 0.14)% 的最高太阳能转换效率，对应于(23.03 ± 0.2) mA cm ^–2的J _sc和(0.54 ± 0.01) V 的V _oc .
