Abstract: Dye-sensitized solar cells (DSSCs) provide a promising alternative to traditional solar technologies, as they offer a unique mix of cost-effectiveness, adaptability, and the possibility of achieving high efficiency.This study aims to investigate the effect of SiO 2 purity obtained from coal fly ash on the photoelectric performance of DSSCs.The study focuses on varying the purity of extracted SiO 2 from coal fly ash as a counter-electrode material and examining its impact on the efficiency of DSSCs.The efficiency of DSSCs was assessed by evaluating the performance of several various SiO 2 purity materials for counter-electrode materials.The performance testing of DSSCs revealed that the counter electrode material, consisting of artificial SiO 2 with a purity of 99.9%, achieved the highest efficiency of 0.0113%.Subsequently, DSSCs were fabricated using counter-electrode materials derived from coal fly ash with a purity of 52.91%.These DSSCs demonstrated an efficiency of 0.0076%.DSSCs utilizing SiO 2 with a purity of 91.20% exhibited an efficiency of 0.0062%.Dye-sensitized solar cells utilizing a counter electrode material composed of SiO 2 with a purity level of 72.54% demonstrated an efficiency of 0.0061%.The results showed that the level of SiO 2 purity obtained from coal fly ash has a substantial impact on the photoelectric performance of DSSCs, since higher purity of SiO 2 is associated with improved efficiency.
