共轭聚合物在有机太阳能电池中有着悠久的探索和应用历史，在过去的25年里，太阳能电池的效率得到了显着的提高。然而，这些材料的合成复杂性也急剧增加，这使得最高效材料的可扩展性变得困难。如果共轭聚合物可以被设计成既高效又简单的合成，那么通往商业现实的道路将更容易实现。为此，设计了一种新的合成方法用于PTQ 10（=聚[（噻吩）-alt-（6，7-二氟-2-（2-己基癸氧基）喹喔啉）]）。PTQ 10的新合成方法大大降低了成本（是原来的1/7），并且还可以轻松容纳不同的侧链，从而向绿色加工溶剂发展。此外，用PTQ 10：Y 6共混物展示了高效率有机太阳能电池，其表现出约15%的效率。
Conjugated polymers have a long history of exploration and use in organic solar cells, and over the last twenty-five years, marked increases in the solar cell efficiency have been achieved. However, the synthetic complexity of these materials has also drastically increased, which makes the scalability of the highest-efficiency materials difficult. If conjugated polymers could be designed to exhibit both high efficiency and straightforward synthesis, the road to commercial reality would be more achievable. For that reason, a new synthetic approach was designed towards PTQ10 (=poly[(thiophene)-alt-(6,7-difluoro-2-(2-hexyldecyloxy)quinoxaline)]). The new synthetic approach to make PTQ10 brought a significant reduction in cost (1/7th the original) and could also easily accommodate different side chains to move towards green processing solvents. Furthermore, high-efficiency organic solar cells were demonstrated with a PTQ10:Y6 blend exhibiting approximately 15 % efficiency.
