Due to the unique three-dimensional spatial structure and special electronic properties, triptycene has been applied in dye-sensitized solar cells. Herein, two dyes JY76/JY77 featuring triptycene at the different substitution position of carbazole donor have been synthesized, and location effect of triptycene on the photovoltaic performance of devices has been investigated. Lateral derived triptycene endows JY77 much more enhanced capability of impeding the interface charge recombination than JY76 which triptycene was decorated at terminal. Finally, JY77-sensitized solar cells exhibit around 20% higher power conversion efficiency (PCE) than that of JY76. The photovoltaic properties are further tuned by co-sensitization strategy, and better PCEs are obtained. Under AM 1.5G irradiation, cells fabricated by the synergic adsorption of JY77 and JY75, achieve the highest PCE of 8.01%. In the experiment, the researchers used many compounds, for example, 1-Bromopyrrolidine-2,5-dione (cas: 128-08-5SDS of cas: 128-08-5).
1-Bromopyrrolidine-2,5-dione (cas: 128-08-5) belongs to organobromine compounds. Bromo compounds are employed in a variety of metal-catalyzed coupling reactions. They are also ideal candidates for the synthesis of Grignard reagents that have wide-applicability in organic synthesis. alpha-Bromoesters are employed in the Reformatsky reaction for the synthesis of beta-hydroxyesters. In the pharmaceutical industry organo bromine derivatives are used as sedatives, vasodilators, antiseptic agents, and anticancer agents.SDS of cas: 128-08-5
