An inexpensive material,i.e.,tetranuclear zinc(Ⅱ) complex,(Zn4O(AID)6) [AID = 7-azaindolate],was utilized as a cathode buffer in organic photovoltaic(OPV) devices,leading to the improvement of device performance.Compared to OPV devices based on a conventional cathode buffer of TPBi(1,3,5-tris(2-N-phenylbenzimidazolyl)benzene),although the freshly prepared devices showed similar performance,when heated to a series of high temperatures under air,the short circuit current and the open circuit voltage of the Zn4O(AID)6 devices dropped more slowly,indicating the superiority of using Zn4O(AID)6 as a cathode buffer over TPBi in OPV devices.
An inexpensive material, ie, tetranuclear zinc (II) complex, (Zn4O (AID) 6) [aID = 7-azaindolate] was utilized as a cathode buffer in organic photovoltaic (OPV) devices, leading to the improvement of device performance. Compared to OPV devices based on a conventional cathode buffer of TPBi (1,3-tris (2-N-phenylbenzimidazolyl) benzene), although the freshly prepared devices showed similar performance, when heated to a series of high temperatures under air, the short circuit current and the open circuit voltage of the Zn4O (AID) 6 devices dropped more slowly, indicating the superiority of using Zn4O (AID) 6 as a cathode buffer over TPBi in OPV devices.
