TPT10 has a very similar structure to both Y6 and Y7 except that the peripheral end groups are mono-brominated instead of being either bis-fluorinated or chlorinated. With fewer bromine substitutes, TPT10 shows a better solubility in common solvents.
TPT10 has been successfully used with PTQ10 and PTQ11 to produce potentially low-cost high efficiency polymer organic solar cells with a reported PCE of 16.32%, a step closer for commercialisation of such devices.
