An alkyl-thiophene functionalized D-π-A porphyrin (LW16) is designed and synthesized for dye-sensitized solar cells (DSSCs). Two hexyl-thiophene groups are attached to the meta-position of each meso-phenyl with a motivation to increase the light-harvesting ability as well as retarding the aggregation of porphyrins dyes. For comparison, none-alkyl substituted (LW14) and octyloxy substituted (LW15)...
Sensitizers have proven to be extremely important in determining the performance of dye-sensitized solar cells (DSCs). The design and understanding of sensitizers, especially D-π-A structured porphyrins, has become a recent focus of DSC research. In this perspective article, advances in the conception and performance of various sensitizers including ruthenium complexes, organic dyes and porphyrins...
