Co-sensitization is a popular route towards improved efficiency and stability of dye-sensitized solar cells (DSSCs). In this context, the power conversion efficiency (PCE) values of DSSCs incorporating Ru- and porphyrin-based dyes can be improved from 8-11 % to 11-14 % after the addition of additives, co-adsorbents, and co-sensitizers that reduce aggregation and charge recombination in the device. Among the three supporting material types, co-sensitizers play a major role to enhance the performance and stability of DSSCs, which is requried for commercialization. In this Minireview, we highlight the role co-sensitizers play in improving photovoltaic performance of devices containing Ru- and porphyrin-based sensitizers.
共敏化是提高染料敏化太阳能电池（DSSC）效率和稳定性的常用途径。在此背景下，添加可减少器件中聚集和电荷复合的添加剂、共吸附剂和共敏化剂后，含有钌基和卟啉基染料的DSSC的功率转换效率（PCE）值可从8 - 11%提高到11 - 14%。在这三种辅助材料类型中，共敏化剂在提高DSSC的性能和稳定性方面起着主要作用，而这是商业化所必需的。在本综述中，我们重点介绍了共敏化剂在提高含钌基和卟啉基敏化剂器件的光伏性能中所起的作用。
