| Popis: | Three novel conjugated polymers incorporating extended DADAD and DADADAD building blocks with the 5,6-bisalkoxybenzoxadiazole acceptor (A) and the electron donor (D) thiophene units were synthesized and fully characterized. The application of the benzoxadiazole instead of benzothiadiazole resulted in a significant increase in the open circuit voltage of organic solar cells based on such polymers. The best performing material delivered a decent solar light power conversion efficiency of 5.5% in organic bulk heterojunction solar cells using PC 71 BM as an electron acceptor component. The obtained results revealed a high potential of using different acceptor building blocks in the design of novel (-X-DADAD-) n polymers with tailored optoelectronic and photovoltaic properties. |
