Dye‐sensitized cells (DSCs) are promising photovoltaic technology that converts photon energy to electric energy efficiently in direct sunlight and ambient indoor light. While most papers address this triumph by utilizing novel materials such as new sensitizers, new redox couples, or new architecture, herein, we report a different approach, which progressively improves a dim light‐illuminated DSC's performance based on commercially mature materials. Specifically, the thickness of the mesoscopic TiO₂ film, the preferred facet of TiO₂ nanoparticles, the quality of compact layer, and iodine/iodide concentration are stepwisely optimized based on the consideration of dim light condition. Finally, the conversion efficiency of a DSC under extreme dim of 50‐lux fluorescent light is improved from 2.43% to 14.86%, accordingly.

在50 lux暗光下逐步优化染料敏化电池的光伏性能

染料敏化电池（DSC）是有前途的光伏技术，可在阳光直射和室内室内光下将光子能量有效地转换为电能。尽管大多数论文通过利用新型材料（例如新型敏化剂，新型氧化还原对或新型结构）来解决这一问题，但我们在此报告了另一种方法，该方法基于商业上成熟的材料逐渐改善了昏暗照明DSC的性能。具体而言，介观TiO 2的厚度₂膜，TiO 2的优选的小面₂基于暗光条件，逐步优化了纳米粒子，致密层的质量以及碘/碘化物的浓度。最后，DSC在50勒克斯荧光灯的极端暗淡条件下的转换效率从2.43％提高到14.86％。
