Developing gel polymer electrolyte (GPE) can solve the safety issues faced by liquid electrolyte and allow easy fabrication of dye-sensitized solar cell (DSSC). However, its power conversion efficiency (η) still needs improvement by bettering any other parameters such as open-circuit voltage (V_OC), short–circuit current (J_SC) and Fill Factor (FF). Herein, 4-tert-butyl-pyridine (TBP) is used as an additive with different concentrations, and its effects on the GPE-TBP are studied. The addition of TBP is beneficial in DSSC employing GPE-TBP as it can adsorb on the surface of the mesoporous TiO₂ photoanode, which leads to the shifting of the quasi-fermi level of TiO₂ photoanode to a higher potential. This phenomenon enhances open-circuit voltage (V_OC) of the DSSC from 615 to 750 mV upon addition of 7 wt% of TBP content to the GPE sample. However, taking into consideration all parameters in DSSC employing GPE-TBP, GPE sample containing 3 wt% of TBP shows the highest photovoltaic conversion efficiency (ɳ) of 8.11% under light illumination of 100 mW cm⁻².

研发凝胶聚合物电解质（GPE）可以解决液体电解质面临的安全问题，并易于制造染料敏化太阳能电池（DSSC）。但是，其功率转换效率（η）仍需要通过改善任何其他参数来改善，例如开路电压（V _OC），短路电流（J _SC）和填充因数（FF）。在此，使用4-叔丁基吡啶（TBP）作为不同浓度的添加剂，并且研究了其对GPE-TBP的影响。添加TBP的是在DSSC采用GPE-TBP有益的，因为它可以在介孔二氧化钛的表面上吸附₂光电阳极，这导致TiO 2的准费米能级的移动₂光电阳极具有更高的潜力。当向GPE样品中添加7 wt％的TBP含量时，此现象会将DSSC的开路电压（V _OC）从615提高到750 mV。然而，考虑到所有参数在DSSC采用GPE-TBP，含有的TBP示出了最高的光电转换效率（3重量％GPE样品ɳ的8.11％）在100毫瓦厘米的光照明^-2。
