✦ Synopsis

Abstract

The synthesis of two ruthenium terpyridine complexes containing conjugated polymers is reported and their application as photosensitizers in dye‐sensitized solar cells (DSSC) was studied. The polymers were synthesized by the palladium‐catalyzed coupling reaction between the ruthenium complex monomer and the fluorene‐based comonomer. One polymer was functionalized with carboxylic acid groups on the main chain, which strongly facilitate the anchorage of polymer dye molecules on the electrode surface. DSSCs based on TiO~2~ nanoparticles and nanotubes were fabricated. It was found that the ruthenium complexes played an important role in the photosensitization process, and the power conversion efficiencies measured were in the order of 0.1%. Annealing of TiO~2~ nanotubes in ammonia gas flow did not result in significant improvement in cell performance. magnified image

## Abstract In order to improve the performance of ZnO‐based solar cells, highly‐ordered hierarchical ZnO nanostructures were design and fabricated. The hierarchical nanostructures were grown on FTO (fluorine doped tin oxide, SnO~2~:F) glass substrates via a facile, low‐temperature, and low‐cost ch
