| 英文摘要 | Two novel D-pi-A-pi-D-type small molecules (SMs) of IID(Ac-Py)(2) and IID(Th-Py)(2) were synthesized and characterized, in which isoindigo (IID), acetylene (Ac) or thiophene (Th), and pyrene (Py) were used as the acceptor (A) core, extended pi-bridges, and donor (D) terminal units, respectively. Significantly improved photophysical and photovoltaic performances were observed for both SMs containing extended pi-bridge in comparison with those for their parent D-A-D type molecule of IID(Py)(2). Compared to IID(Ac-Py)(2), IID(Th-Py)(2) shows a better photovoltaic performance due to broader absorption, deeper HOMO levels (-5.44 eV) and better morphology of the devices. A maximum power conversion efficiency (PCE) of 1.88% with a short-circuit current density Usc) of 6.90 mA cm(-2) was obtained in the IID(Th-Py)(2)/PC71BM-based solar cells, which is 235 times the value of IID(Ac-Py)(2)-based cells. Particularly, the IID(Th-Py)(2)/PC61BM-based device exhibited a Vac value up to 1.01 V, which is 0.27 V and 0.12 V higher than IID(Py)(2)/and IlD(Ac-Py)(2)/PC61BM-based devices, respectively. To our best knowledge, the Vac of 1.01 V is among the highest values in literature for solution processed SMs OSCs without any post processing. (C) 2016 Published by Elsevier Ltd. |
