Abstract

Abstract: 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. Abstract : Better together : Co‐sensitizers are important additives that reduce charge recombination and aggregation processes in dye‐sensitized solar cells, improving the power conversion efficiency and stability of devices. Various co‐sensitizers are incorporated in devices implementing both Ru‐ and porphyrin‐based dyes, leading to remarkable power conversion efficiency values and demonstrating their role towards improved device performance.
