TPT10 for low-cost, highly efficient organic polymer solar cells

Available to buy online with free shipping on qualifying orders

TPT10 is a non-fullerene acceptor molecule with a very similar chemical structure to both Y6 and Y7. The only structural difference between TPT10 and Y6 or Y7 is that TPT10 has mono-brominated peripheral end groups. Y6 and Y7, by comparison, have bis-fluorinated and chlorinated end groups respectively. With fewer bromine substitutes, TPT10 shows a better solubility in common solvents. This property is exaggerated in TPT10-C8C12, which has larger butyldodecyl side chains than TPT10.

TPT10 has been successfully used with PTQ10 and PTQ11 to produce low-cost, highly efficient organic polymer solar cells with a reported power conversion efficiency (PCE) of 16.32%. This brings organic photovoltaic (OPV) cells a step closer to viable commercialisation.
