In this study, a polymer gel electrolyte based on polyacrylonitrile was synthesized with varying polymer-to-liquid-electrolyte ratios. DSSCs incorporating a 1:3 ratio showed optimum PV parameters. Choosing this proportion, the effect of incorporating the photoresponsive AZO dye into this polymer electrolyte was studied. When irradiated with a UV light of 365 nm, the AZO dye underwent photoisomerization, which allowed the gel electrolyte to absorb heat from the UV irradiation and increase its ionic conductivity. It was found that by the addition of azopyridine into the polymer electrolyte, there was an improvement in the photovoltaic parameters of cells. By increasing the dye content from 1% to 10% by weight in the electrolyte, an 11% growth in short current density was observed, resulting in about a 10% rise in cell efficiency.
在本研究中，合成了基于聚丙烯腈的聚合物凝胶电解质，其聚合物与液体电解质的比例各不相同。采用1:3比例的染料敏化太阳能电池（DSSCs）显示出最佳的光伏参数。选择该比例后，研究了将光响应性偶氮染料掺入该聚合物电解质中的效果。当用365nm的紫外光照射时，偶氮染料发生光异构化，这使得凝胶电解质能够从紫外辐射中吸收热量并提高其离子电导率。研究发现，通过向聚合物电解质中添加偶氮吡啶，电池的光伏参数得到了改善。通过将电解质中染料含量从1%重量增加到10%重量，观察到短路电流密度增长了11%，导致电池效率提高了约10%。
