Abstract
  • Four new D-?-A organic dyes incorporating either a thiazolo[5,4-d] thiazole bicyclic system (TTZ1-2) or a benzo[1,2-d:4,5-d]bisthiazole tricyclic unit (BBZ1-2) have been synthesized and fully characterized.[1] The key steps of the synthesis include an efficient MW-assisted preparation of the thiazolo-[5,4-d]thiazole core and selective functionalization of two different dihalothienyl derivatives through Suzuki coupling. All the compounds showed photo- and electrochemical properties compatible with their employment in dye-sensitized solar cells.[2] In addition, their electronic structure and transitions were investigated by means of TD-DFT calculations. Dye-sensitized solar cells fabricated with dye TTZ1 yielded an average power conversion efficiency corresponding to 43 and 60% of the performances recorded under the same conditions for cells containing reference dyes N3 and D5, respectively. The use of chenodeoxycholic acid (CDCA) as a co-adsorbent was beneficial to disrupt dye-dye interactions and slow down recombination processes within the cells, thus allowing power conversion efficiencies up to 3.53% to be obtained.
