PTQ10 is a donor–acceptor (D–A) type copolymer with a simple thiophene ring as the electron donor unit and quinoxaline (QX) as electron acceptor unit. The alkoxy side chain attached on quinoxaline unit is to promote solubility and to enhance absorption of of the targeted polymer. Difluoro substituted quinoxaline can further down-shift the HOMO energy level, achieve fast charge separation and low nonradiative recombination loss in the PSCs leading to high VOC and JSC.

Comparing with some other polymer semiconducting materials, PTQ10 has a simple structure which could lead to mass production with low cost. PTQ10 can also be processed in solution with eco-friendly non-halogenated solvents, i.e. o-xylene. The combined effects of high efficiency, low cost and green solvents processibility makes PTQ10 an ideal candidate for large scale doctor-blading and inkjet printing device fabrications.

Organic polymer solar cells based on PTQ10:Y6 blend shows efficient charge separation, higher photoluminescence quenching efficiency and higher charge mobilities, giving a power conversion efficiency of 16.53%.
